1.14.14.19 additional information CYP17 also exhibits 16alpha-hydroxylase activity towards progesterone in some species, with only human and chimp CYP17 catalysing the biosynthesis of substantial amounts of 16-hydroxy-progesterone. Residue 105 is responsible for the activity, homology modelling, overview Homo sapiens
