Lycopene beta-cyclase

Lycopene β-cyclase (EC 5.5.1.19, CrtL, CrtL-b, CrtY) is an enzyme with systematic name carotenoid beta-end group lyase (decyclizing). This enzyme catalyses the following chemical reaction carotenoid ψ-end group carotenoid β-end group This enzyme requires NAD(P)H. It converts Lycopene (2 ψ ends) into β-carotene (2 β ends). WebAug 8, 2010 · Cyclization of lycopene marks a branching point in the carotenoid biosynthetic pathway: One branch leads to β-carotene and its derivative xanthophylls such as zeaxanthin, violaxanthin, and neoxanthin via hydroxylation of β-carotene hydroxylase ( BCH) and ε-carotene hydroxylase ( ECH ), whereas the other leads to α-carotene and lutein.
