Function

[CP119_SULAC] The endogenous substrate is not known. In vitro, catalyzes the H(2)O(2)-dependent epoxidation of styrene, cis-beta-methylstyrene, and cis-stilbene with retention of stereochemistry. Is able to use cumene hydroperoxide (CHP) or tert-butyl hydroperoxide (TBHP) instead of H(2)O(2) as the electron acceptor. Can also hydroxylate fatty acids such as lauric acid.^{[1] [2] [3]}
