Carotene epsilon-monooxygenase (EC 1.14.99.45, CYP97C1, LUT1) is an enzyme with systematic name alpha-carotene:oxygen oxidoreductase (3-hydroxylating).[1][2] This enzyme catalyses the following chemical reaction

alpha-carotene + O2 + AH2 alpha-cryptoxanthin + A + H2O

Carotene epsilon-monooxygenase is a heme-thiolate protein (P450)..
