Comments |
Requires glutathione. Acts on a range of sterols with a 24(25)-double bond in the sidechain. While zymosterol is the preferred substrate it also acts on desmosterol, 5¦Á-cholesta-7,24-dien-3¦Â-ol, 5¦Á-cholesta-5,7,24-trien-3¦Â-ol, 4¦Á-methylzymosterol and others. S-Adenosyl-L-methionine attacks the Si-face of the 24(25) double bond and the C-24 hydrogen is transferred to C-25 on the Re face of the double bond. |
