Abstract

Using the novel 'substrate-heme complex' approach, the mechanism of 17 alpha-Hydroxylase/17,20-Lyase (P-450(17) alpha), in particular the lyase of the C(17)-C(20) bond, is considered from a geometric perspective. The results of the study appear to suggest that the final oxidative step in the lyase of the C(17)-C(20) bond involves the use of a ferroxy attacking species as opposed to peroxy or a mixture of ferroxy and peroxy, an observation which is consistent with results previously obtained with Aromatase.
