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 $\rightleftharpoons$ lycopene + H₂O
: (2) 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene $\rightleftharpoons$ 1-hydroxy-1,2-dihydrolycopene + H₂O

In '' Rubrivivax gelatinosus'' and '' Thiocapsa roseopersicina'' both products are formed.
