Sysname
lycopene hydro-lyase (1-hydroxy-1,2-dihydrolycopene-forming)
Reaction(IUBMB)
(1) 1-hydroxy-1,2-dihydrolycopene = lycopene + H2O [RN:
R07519 ];
(2) 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene = 1-hydroxy-1,2-dihydrolycopene + H2O [RN:
R09790 ]
Reaction(KEGG)
Substrate
1-hydroxy-1,2-dihydrolycopene [CPD:
C19795 ];
1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene [CPD:
C19894 ]
Product
Comment
In Rubrivivax gelatinosus [1] and Thiocapsa roseopersicina [2] both products are formed, whereas Rhodobacter capsulatus [1] only gives 1-hydroxy-1,2-dihydrolycopene. Also acts on neurosporene giving 1-hydroxy-1,2-dihydroneurosporene with both organism but 1,1'-dihydroxy-1,1',2,2'-tetrahydroneurosporene only with Rubrivivax gelatinosus.
