Carotenoid 1,2-hydratase

Carotenoid 1,2-hydratase (, CrtC) is an enzyme with systematic name lycopene hydro-lyase (1-hydroxy-1,2-dihydrolycopene-forming). This enzyme catalyses the following chemical reaction

(1) 1-hydroxy-1,2-dihydrolycopene lycopene + H<sub>2</sub>O

(2) 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene 1-hydroxy-1,2-dihydrolycopene + H<sub>2</sub>O

In Rubrivivax gelatinosus and Thiocapsa roseopersicina both products are formed.
