Metabolic pathways of acetoin in C. glabrata : the original and heterologous metabolic pathways. The enzymes that catalyze the pathways were: acetolactate synthase (ILV2 + ILV6, ALS), acetolactate decarboxylase (ALDC), pyruvate decarboxylase (PDC); butanediol dehydrogenase (BDH), acetohydroxy acid isomeroreductase (ILV5). The abbreviations are: BCAAs, branched chain amino acids; 3-PG, 3-phosphate-glyceraldehyde; NOD, non-enzymatic oxidative decarboxylation.
