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.

WebMar 29, 2013 · Lycopene β-cyclase (LCYB) is a key enzyme involved directly in the synthesis of α-carotene and β-carotene through the cyclization of lycopene. Carotenoids … WebSep 18, 2009 · The conversion of lycopene to β-carotene is catalysed by the β cyclase enzyme ( Cunningham et al., 1994; Hugueney et al., 1995; Pecker et al., 1996 ). The ϵ and β cyclase enzymes are products of related genes, but the ϵ cyclase only adds one ϵ ring to lycopene, whereas the β cyclase can add two β rings. WebThis enzyme converts lycopene to β-carotene by catalyzing the formation of two β-rings at each end of the linear carotene. The enzyme interacts with half of the carotenoid … crystal clear imaging mandeville la
