MF

C-22 sterol desaturase activity

Catalysis of the formation of the C-22(23) double bond in the sterol side chain. An example reaction: 5,7,24(28)-ergostatrienol + O2 + NADPH = 5,7,22,24(28)-ergostatetraenol + 2 H2O + NADP+.

MF

monooxygenase activity

Catalysis of the incorporation of one atom from molecular oxygen into a compound and the reduction of the other atom of oxygen to water.

GO:0005506

MF

iron ion binding

Interacting selectively and non-covalently with iron (Fe) ions.

GO:0005576
