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). Web28 ian. 2014 · Lycopene is cyclized to give rise to two branches in the carotenoid biosynthetic pathway, the β,ε branch and the β,β branch. The generation of α-carotene from the β,ε branch is dependent on lycopene epsilon cyclase (LCYε) and lycopene beta cyclase (LCYβ); the generation of β-carotene from the β,β branch is dependent on LCYβ.
