Lycopene beta/epsilon cyclase protein

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 are produced in both carrot ( Daucus carota) leaves and reserve roots, and high amounts of α-carotene and β-carotene accumulate in the latter. WebOct 1, 2015 · Lycopene cyclization is caused by β-LCY (EC:5.5.1.19) using NADP (H) or FAD as a co-factor ( Hornero-Méndez and Britton, 2002, Yu et al., 2010 ). β-LCY alone produces β-carotene whereas two enzymes, β-LCY and ϵ-LCY (EC: 5.5.1.18), together form α-carotene ( Beyer et al., 1991, Hornero-Méndez and Britton, 2002, Moreno et al., 2013 ).

WebJan 18, 2008 · The first branch point of this pathway occurs at cyclization of lycopene where action of lycopene beta cyclase (LCYB) at both ends of linear lycopene produces a molecule with two β rings. Alternatively, the coaction of LCYB and lycopene epsilon cyclase (LCYE) generates a β,ϵ-carotene that is a precursor to lutein ( 13 ). http://pfam-legacy.xfam.org/family/PF05834 mckinley rice noida
