Redox control of the P450cam catalytic cycle: effects of Y96F active site mutation and binding of a non-natural substrate.

Abstract excerpt

Spectroelectrochemistry measurements are used to demonstrate that active site mutation and binding of an non-natural substrate to P450cam (CYP101) reduces the shift in the redox potential caused by substrate-binding, and thereby results in slower catalytic turnover rate relative to wild-type enzyme with the natural camphor substrate.
