Pregnenolone 75-87 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 38-45 12788891-8 2003 This resulted in efficient formation of DHEA from pregnenolone, indicating both 17 alpha-hydroxylase and 17,20-lyase activities exerted by P450c17. Pregnenolone 50-62 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 139-146
