Overview of main metabolic network of lignin conversion to lipid in Rhodococci. Compared to samples from glucose fermentation, abbreviations for proteins upregulated in lignin-fed Rhodococci are presented in red (* indicates that the given protein was significantly upregulated in our previous [9] work), whereas downregulated proteins in lignin-fed Rhodococci are presented in blue; the abbreviations for proteins with increased oxidation levels at the reported cysteine thiols are shown in orange boxes, whereas protein cysteine sites with decreased oxidation level are shown in green boxes. Proteins written in black were observed but significant differences in expression were not
