Title	N-terminal-oriented proteogenomics for the marine bacterium Roseobacter denitrificans
Description	Given the facilities for whole genome sequencing with next-generation sequencers, structural and functional gene annotation is now only based on automated prediction. However, errors in terms of gene structure are still frequently reported especially for the correct determination of initiation start codons. Here, we propose a strategy to enrich and detect protein N-termini by mass spectrometry in order to refine genome annotation. After selective protein N-termini derivatization using (N-Succinimidyloxycarbonylmethyl)tris(2,4,6-trimethoxyphenyl)phosphonium bromide (TMPPAc-OSu) as labeling reagent, protein digestion was performed with three proteases in parallel. TMPP-labeled N-terminal-most peptides were further resolved from internal peptides by the COmbined FRActional DIagonal Chromatography (COFRADIC) sorting methodology before analysis with tandem mass spectrometry. We refined the annotation of the genome of a model marine bacterium, Roseobacter denitrificans.
