Improving astaxanthin production in Escherichia coli by co-utilizing CrtZ enzymes with different substrate preference
Abstract Background The bifunctional enzyme β-carotene hydroxylase (CrtZ) catalyzes the hydroxylation of carotenoid β-ionone rings at the 3, 3’ position regardless of the presence of keto group at 4, 4’ position, which is an important step in the synthesis of astaxanthin. The level and substrate pre...
