Quantitative proteomic analysis of the microbial degradation of 3-aminobenzoic acid by Comamonas sp. QT12.

ABSTRACT: A mab cluster associated with 3-aminobenzoic acid (3AB) degradation was identified in Comamonas sp. QT12. However, the cellular response of Comamonas sp. QT12 to 3-aminobenzoic acid remains unclear. In this study, label-free quantitative proteome analysis based on LC-MS/MS was used to study the protein expression difference of strain QT12 under the condition of using 3AB (3AB) and citric acid/ammonium chloride as substrates (3ABCon). A total of 2068 proteins were identified, of which 239 were significantly up-regulated in 3AB group, 124 were significantly down-regulated in 3AB group, 624 were expressed only in 3AB group, and 216 were expressed only in 3ABCon group in 3AB group. KEGG pathway analysis found that 83 pathways were up-regulated and 49 pathways were down-regulated, In GO analysi
