Carotenoid 1,2 hydratase

Carotenoid 1,2-hydratase (EC 4.2.1.131, 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 + H₂O (2) 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene ⇌ 1-hydroxy-1,2-dihydrolycopene + H₂O

In Rubrivivax gelatinosus and Thiocapsa roseopersicina both products are formed.
