Jehmlich N, Dinh H, Gesell Salazar M, Hammer E, Steil L, Dhople V, Schurmann C, Teumer A, Holtfreter B, Kocher T, Völker U
Journal of Proteome Research submitted

Intra- and inter-subject variability of unstimulated whole saliva samples of four subjects was compared at different time-points using two quantitative proteomic techniques, namely gel-based (2-D DIGE) and gel-free (LC-MS/MS) approaches. Both methods are suitable for biomarker screening in whole saliva and might be used most efficiently in combination because they complementary cover protein and peptide level, respectively.

26_Protein-based stable isotope probing in functional metaproteomics
Seifert J, Taubert M, Jehmlich N, Schmit F, Völker U, Vogt C, Richnow HH, von Bergen M
Mass Spectrometry Reviews revision

The classical metaproteome approaches will be reviewed with an emphasis on their attempts towards functional interpretation. The gain from functional insights into metaproteomics by using metabolic labeling of stable isotopes of carbon, nitrogen and sulfur is reviewed with a focus on the techniques of measurement, calculation of incorporation and data processing.

Jehmlich N, Kopinke FD, Lenhard S, Vogt C, Herbst FA, Seifert J, Lissner U, Völker U, Schmidt F, von Bergen M
Proteomics (2012) Jan 12(1):37-42

Sulfur-(36) S stable isotope (SULAQ) technology can be a valuable alternative strategy for the quantitative comparisons in MS-based proteomics approaches characterizing bacterial and other biological samples in different growth conditions.

24_Identification of spore specific allergens from Penicillium chrysogenum
Goodman V, Müller A, Gröger-Arndt H, Schlosser D, Jehmlich N, Treudler R, Lehmann I, Simon JC, von Bergen M
Journal of integrated OMICS (2011) 1(2):272-279

The common indoor mould Penicillium chrysogenum is reported to be associated with respiratory diseases and allergic asthma. Beside the already known specific allergens stemming from mixtures of hyphae and spores the question was which allergens are specifically abundant in the airborne spores.

23_Time resolved protein-based stable isotope probing (Protein-SIP) analysis allows quantification of induced proteins in substrate shift experiments
Taubert M, Jehmlich N, Vogt C, Richnow HH, Schmidt F, von Bergen M, Seifert J
Proteomics (2011) Jun;11(11):2265-74

In this study, Protein-SIP is used for a fast and reliable detection of newly synthesized proteins in a substrate shift experiment.

22_Protein based stable isotope labeling
Jehmlich N, Schmidt F, Taubert M, Seifert J, von Bergen M, Richnow HH, Vogt C
Nature Protocols (2010) Dec;5(12):1957-66

In this article, we provide guidelines for incubating microbial cultures with labeled substrates and a protocol for Protein-SIP. The protocol guides readers through the proteomics pipeline, including protein extraction, gel-free and gel-based protein separation, the subsequent mass spectrometric analysis of peptides and the calculation of the incorporation of stable isotopes into peptides.

Jehmlich N, Hübschmann T, Gesell Salazar M, Völker U, Benndorf D, Müller S, von Bergen M, Schmidt F
Applied Microbiology and Biotechnology (2010) Sep;88(2):575-84

A workflow was developed to analyze successfully microbial sorted cells by downstream analysis of proteomics. Cytometric analysis and cell sortinng of sub-populations of interest are the prerequisites for a successful subsequent application of Omics-technologies. Therefore, we applied a filter device approach that enabled a comprehensive proteomic approach by LC-MS.

19_Declining capacity of starving Deltia acidovorans MC1 to degrade phenoxypropionate herbicides correlates with oxidative modification of the initial enzyme
Leibeling S, Schmidt F, Jehmlich N, von Bergen M, Müller RH, Harms H
Environmental Science & Technology (2010) May 15;44(10):3793-9

Starving Deltia acidovorans MC1 were found to lose specific degradation activity, while accumulating variants of the alpha-ketoglutarate-dependent dioxygenase RdpA, the enzyme initiating the degradation of (RS)-2-(2,4-dichlorophenoxy)propionate. These variants differed in their pI and originated from post-translational modification, since there is only one rdpA gene in the genome.

Harms H, Müller S
Cytometry Part A (2010) Feb;77(2):113-20

In this study, a fluorescently labeled toluene analogue dye (3-(N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)-3-toluene; NBDT), flow cytometry, and shot gun proteome analysis were used to follow toluene uptake into bacteria in more detail.

14_Gene clusters involved in anaerobic 2-methylnaphthalene degradation of the sulfate-reducing enrichment culture N47
Selesi D, Jehmlich N, von Bergen M, Schmidt F, Rattei T, Tischler P, Lueders T, Meckenstock RU
Journal of Bacteriology (2010) Jan;192(1):295-306

The work provides the first insight into the genetic basis of anaerobic 2-methylnaphthalene metabolism and delivers implications for understanding contaminant degradation. Proteome analysis of 2-methylnaphthalene- grown N47 cells resulted in the identification of putative enzymes catalyzing the anaerobic conversion of 2-methylnaphthalene to 2-naphthoyl coenzyme A (2-naphthoyl-CoA), as well as the reductive ring cleavage of 2-naphthoyl-CoA, leading to the formation of acetyl-CoA and CO2.

13_Octapeptide NMHRYPNQ of the celluar prion protein (PrPc) inhibits aggregation and its a potential key for understanding prion prion interactions
Rehders D, Claasen B, Redecke L, Buschke A, Reibe C, Jehmlich N, von Bergen M, Betzel C, Meyer B
Journal of Molecular Biology (2009) Sep 11;392(1):198-207

Knowledge of molecules that inhibit such contacts leads to an understanding of the mechanism of the aggregation, and these molecules may serve as leads for drugs against transmissible spongiform encephalopathies. Therefore, we screened a synthetic octapeptide library of the globular domain of the human PrP(C) for binding affinity to PrP(C).

12_Comparison of methods for simultaneous identification of bacterial species and determination of metabolic activity by protein-based stable isotope probing (Protein-SIP) experiments
Jehmlich N, Schmidt F, Taubert M, von Bergen, Richnow HH, Vogt C
Rapid Communications in Mass Spectrometry (2009) June; 23(12): 1871-1878

The Protein-SIP concept was tested using two more gel-free proteomic methods namely intact protein profiling (IPP) and shotgun mass mapping (SMM). Whereas SMM revealed a higher robustness of species identification by mass spectrometry and a higher certainty of incorporation level calculation compared to IPP.

11_Decarboxylating and nondecarboxylating glutaryl-coenzyme A dehydrogenases in the aromatic metabolism of obligately anaerobic bacteria
Wischgoll S, Taubert M, Peters F, Jehmlich N, von Bergen M, Boll M
J Bacteriol (2009) Jul;191(13):4401-9

In anaerobic bacteria using aromatic growth substrates, glutaryl-coenzyme A (CoA) dehydrogenases (GDHs) are involved in the catabolism of the central intermediate benzoyl-CoA to three acetyl-CoAs and CO(2). In this work, we studied GDHs from the strictly anaerobic, aromatic compound-degrading organisms Geobacter metallireducens (GDH(Geo)) (Fe[III] reducing) and Desulfococcus multivorans (GDH(Des)) (sulfate reducing).

10_Biochemical and molecular genetic characterisation of a novel dimeric laccase with an alkaline isoelectric point produced by the aquatic ascomycete Phoma sp. UHH 5-1-03
Junghanns C, Böhm D, Pecyna M, Jehmlich N, Martin C, von Bergen M, Schauer F, Schlosser D
Applied Microbiology and Biotechnology (2009) Oct;84(6):1095-105

A laccase from the aquatic ascomycete Phoma sp. UHH 5-1-03 (DSM 22425) was purified. Mass spectrometric analysis of the laccase monomer yielded a molecular mass of 75.6 kDa. The enzyme possesses an unusual alkaline isoelectric point above 8.3. The Phoma sp. laccase undergoes pH-dependent dimerisation, with the dimer (approximately 150 kDa, as assessed by SEC) predominating in a pH range of 5.0 to 8.0.

Schleinitz KM, Schmeling S, Jehmlich N, von Bergen M, Harms H, Kleinsteuber S, Vogt C, Fuchs G
Applied and Environmental Microbiology (2009) Jun;75(12):3912-9

We investigated phenol degradation in the strictly anaerobic iron-reducing deltaproteobacterium Geobacter metallireducens GS-15 using metabolite, transcriptome, proteome, and enzyme analyses. The results showed that the initial steps of phenol degradation are accomplished by phenylphosphate synthase (encoded by pps genes) and phenylphosphate carboxylase (encoded by ppc genes) as known from Thauera aromatica, but they also revealed some distinct differences.

7_Snake venomics of the siamese russell viper (Daboia russelli siamensis) relation to pharmacological activities
Risch M, Georgieva D, von Bergen M, Jehmlich N, Genov N, Arni RK, Betzel C
Journal of Proteomics (2009) March 6, 72(2):256-269

The proteome comprises toxins from six protein families: serine proteinases, metalloproteinases, phospholipases A(2), L-amino acid oxidases, vascular endothelial growth factors and C-type lectin-like proteins. The venom toxin composition correlates with the clinical manifestation of the Russell viper bite and explains pathological effects of the venom such as coagulopathy, oedema, hypotensive, necrotic and tissue damaging effects.

Johannes J, Bluschke A, Jehmlich N, von Bergen M, Boll M
Journal of Bacteriology (2008) Oct,190(19):6493-500

The soluble components of this complex were purified and characterized. The data obtained suggest a molecular mass of 124 +/- 15 kDa and a unique alpha alpha beta(2) subunit composition, with alpha and alpha?representing isoforms of the flavin adenine dinucleotide (FAD)-containing subunit and beta representing a c-type cytochrome.

5_Incorporation of carbon and nitrogen atoms into proteins measured by protein based stable isotope probing (Protein-SIP)
Jehmlich N, Schmidt F, Hartwich M, von Bergen M, Richnow HH, Vogt C
Rapid Communications in Mass Spectrometry (2008) Sep; 22(18): 2889-2897

The concept of Protein-SIP was evaluated by analysing the metabolic incorporation of stable isotopes into the proteins of an aerobic benzene-metabolizing microorganism (Pseudomonas putida ML2) in a proof-of-principle approach. The substrates (12)C-benzene, (13)C-benzene or (15)N-ammonium and (12)C-benzene were applied to monitor the heavy stable isotope incorporation into proteins by matrix-assisted laser ionization/desorption mass spectrometric (MALDI-MS) analysis.

4_Aromatizing cyclohex-1,5-diene-1-carbonyl-coenzyme A oxidase: initial characterization and its role in anaerobic aromatic metabolism
Thiele B, Rieder O, Jehmlich N, von Bergen M, Müller M, Boll M
Journal of Biological Chemistry (2008) Jul 25; 283(30):20713-21

In extracts from anaerobically grown denitrifying Thauera aromatica, we detected a benzoate-induced, benzoyl-CoA-forming, 1,5-dienoyl-CoA:acceptor oxidoreductase activity. This activity co-purified with BCR but could be partially separated from it by hydroxyapatite chromatography. After activity staining on native gels, a monomeric protein with a subunit molecular weight of M(r) 76,000 was identified.

3_Protein based stable isotope probing (Protein-SIP) reveals active species within anoxic mixed cultures
Jehmlich N, Schmidt F, von Bergen M, Richnow HH, Vogt C
ISME Journal (2008) Nov 2(11):1122-33

Incorporation of (13)C was exclusively found in proteins from strain EbN1 at a content of 82.6+/-2.3%, as an average calculated from 19 proteins, demonstrating the suitability of the method used to identify metabolic active species with specific properties within a mixed culture.

2_Purification and characterization of a laccase from the aquatic fungus Myrioconium sp. UHH 1-13-18-4 and analysis of the laccase-encoding gene
Martin C, Pecyna M, Kellner H, Jehmlich N, Junghanns C, Benndorf D, von Bergen M, Schlosser D
Applied Microbiology and Biotechnology (2007) Dec;77(3) 613-624

An extracellular, monomeric, and glycosylated laccase with a molecular mass of 72.7 kDa and an isoelectric point below 2.8 was purified from CuSO(4) and vanillic acid amended liquid fungal cultures grown in malt extract medium.

1_Detection, quantification and identification of fungal extracellular laccases using polyclonal antibody and mass spectrometry
Kellner H, Jehmlich N, Benndorf D, Hoffmann R, Rühl M, Hoegger PJ, Majcherczyk A, Kües U, von Bergen M, Buscot F
Enzyme and Microbial Technology (2007) 41:694-701

The polyclonal anti-laccase antibody LccCbr2 was raised against peptides designed from the copper binding region 11 of fungal laccases using in silico data obtained from GenBank database. As a consequence, detection requires denaturation of the enzymes due to the stable conformation of the copper binding region II. The specificity of the antibody was shown with denatured laccase Lcc1 of Coprinopsis cinerea and laccase of Hypholoma fasciculare.
