Relative abundance and phylogenetic origin of bacterial enzymes involved in butyrate, propionate and acetate production in the metaproteomes of RWS and TWS (1 and 2 indicate the biological duplicates). Taxonomic affiliation of proteins at the genus level. Proteins belonging to the same bacterial phylum were represented with the same color palette: Bacteroidetes (Bacteroidota) (blue), Firmicutes (Bacillota)(red) and Proteobacteria (Pseudomonadota) (green). For butyrate biosynthesis: COG4770 (acetyl/propionyl-CoA carboxylase), COG3426 (butyrate kinase), COG1250 (3-hydroxyacyl-CoA dehydrogenase), COG1024 (enoyl-CoA hydratase), COG0183 (acetyl/butyryl-CoA acetyltransferase), COG1979 (alcohol dehydrogenase YqhD), COG1454 (alcohol dehydrogenase, class IV), COG1028 (short-chain alcohol dehydrogenase), COG1064 (Zn-dependent alcohol dehydrogenase). For propionate biosynthesis: COG4799/0777 (acetyl/propionyl-CoA carboxylase), COG2185/COG1884 (methylmalonyl-CoA mutase), COG0346 (methylmalonyl-CoA epimerase). For acetate production: COG1012 (NAD-dependent aldehyde dehydrogenase), COG0282 (acetate kinase).
