ID 4.2.1.131 DE carotenoid 1,2-hydratase. CA (1) rhodopin = all-trans-lycopene + H2O. CA (2) 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene = H2O + rhodopin. CC -!- In Rubrivivax gelatinosus and Thiocapsa roseopersicina both products CC are formed, whereas Rhodobacter capsulatus only gives 1-hydroxy-1,2- CC dihydrolycopene. CC -!- Also acts on neurosporene giving 1-hydroxy-1,2-dihydroneurosporene CC with both organisms but 1,1'-dihydroxy- CC 1,1',2,2'-tetrahydroneurosporene only with Rubrivivax gelatinosus.
