LITERATURE
expression in Escherichia coli
expression in Escherichia coli. Coexpression of CrtA with acyclic C40 carotenoid pathways can introduce a keto group at the C(2,2') position of unnatural substrates that do not exhibit a C(3,4) double bond. The complete conversion of tetradehydrolycopene to phillipsiaxanthin observed suggests it is a favorable substrate for CrtA activity when compared to the incomplete conversion of lycopene to lycopene-2-one in the presence of CrtA
