Fig. 1From: CRISPRi-mediated metabolic engineering of E. coli for O-methylated anthocyanin productionHeterologous anthocyanin pathway for conversion of the flavan-3-ol substrate (+)-catechin to the O-methylated anthocyanin product peonidin 3-O-glucoside (P3G). Substrate (green) was supplied in media, while cofactors (orange) required for each enzymatic step were co-opted from endogenous E. coli metabolismBack to article page
