A second aminoacid residue of mechanistic importance is Arg15, which is widely conserved among the known alpha class GSTs ( a value of the thiol group, and mutation of Arg15 to Ala or His decreases the steroid isomerase activity by two orders of magnitude, twice the effect of the Tyr9Phe mutation ( The mechanistic studies of human GST A1-1 were extended to human GST A3-3 following the discovery of the latter enzyme ( a value of 6.1 and Tyr9 phenol pK a of 7.9, somewhat lower than the corresponding pK a values of GST A1-1 ( cat value
Collectively, this study forms the basis for future research on hair unpigmentation
