>TIGR01790 carotene-cycl lycopene cyclase family protein; InterPro: IPR010108 Carotenoids have important functions in photosynthesis, nutrition, and protection against oxidative damage, and are essential components of the photosynthetic membranes in all plants, algae, and cyanobacteria. The final steps in the biosynthesis of carotenoids usually involve the cyclization of lycopene by one of two pathways: the formation of a beta ring by beta-cyclase, or an epsilon ring by epsilon-cyclase. Epsilon-cyclase adds only one ring, forming the monocyclic delta-carotene, whereas beta-cyclase introduces a ring at both ends of lycopene to form the bicyclic beta-carotene . Both enzymes show high sequence similarities, and may have evolved from the same ancestor . This family includes lycopene beta-and epsilion-cyclases, which are involved in the biosynthesis of carotenoids in bacteria and plants, and the related capsanthin capsorubin synthase (Ccs) from plants, which converts antheraxanthin or violaxanthin into capsanthin or capsorubin by a mechanism similar to lycopene cyclization.; GO: 0016705 oxidoreductase activity acting on paired donors with incorporation or reduction of molecular oxygen, 0016117 carotenoid biosynthetic process.
