Fig. 5From: Understanding of bacterial lignin extracellular degradation mechanisms by Pseudomonas putida KT2440 via secretomic analysisProposed lignin degradation pathways with P. putida secretome. The lignin linkages, final degradation products and enzymes in the pathway map are identified by NMR, GC–MS and proteomics analysis in this study, and the reaction mechanisms are cross-validated by previous literature [27, 37, 40,41,42, 44, 48, 57, 69]. Abbreviations of enzyme: Dyp, Dyp-type peroxidase (PP_3248); CopA, multicopper oxidase (copA-II); GST, glutathione S-transferase (PP_1644); gor, glutathione reductase; betA, choline dehydrogenase; PP_5154, FAD-binding oxidoreductase; aldA/aldB-I, aldehyde dehydrogenase.
