Fig. 1From: Construction of Escherichia coli cell factories for crocin biosynthesisHeterologous crocetin and crocin biosynthesis pathways initiated from zeaxanthin. Crocin-1, crocin-2, crocin-3 or crocin-4 and crocin-5 were obtained in vitro, and only crocin-5 was obtained in E. coli cellsBack to article page
