Multiple steroid-binding orientations: alteration of regiospecificity of dehydroepiandrosterone 2- and 7-hydroxylase activities of cytochrome P-450 2a-5 by mutation of residue 209.

The mutation of Ala-117 to Val conferred dehydroepiandrosterone (DHEA) hydroxylase activity on cytochrome P-450 2a-4, with the production of both 2 alpha- and 7 alpha-hydroxyDHEA at similar rates. P-450 2a-5 which has Val at position 117, acquired high DHEA hydroxylase activity by mutation of Phe-20...
