Aldehydes 282-291 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 152-157 7578007-3 1995 3 beta-Hydroxyandrost-5-ene-17 beta-carbaldehyde (aldehyde), an analogue of the physiological substrate pregnenolone, was handled as a substrate by both isoforms of CYP17. Aldehydes 40-48 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 165-170 7578007-4 1995 The aldehyde underwent cleavage to produce the 5,16-diene plus the 17 alpha-hydroxyandrogen, at rates approximately 8- and 3-fold higher than any physiological reaction catalyzed, in the absence of cytochrome b5, by the pig and human CYP17 isoforms, respectively. Aldehydes 4-12 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 234-239
