In mammals, two carotenoid cleaving oxygenases are known; beta-carotene 15,15'-monooxygenase (BCMO1) and beta-carotene 9',10'-oxygenase (BCO2). BCMO1 is a key enzyme in vitamin A synthesis by symmetrically cleaving beta-carotene into 2 molecules of all-trans-retinal, while BCO2 is responsible for asymmetric cleavage
