DELTA31
-
deletion of the N-terminal 31 residues, kinetic parameters KM and kcat are essentially the same as those of the wild-type. It forms a tetramer in solution, which is similar to the wild-type but is less stable. Melting temperature is 48C, which is lower than that of the wild-type (52C)
H68D
-
produces (R)-enantiomer with low optical purity and yield
H68D/P69D
-
produces (R)-enantiomer with low optical purity and yield
P69D
-

D218V
single nucleotide polymorphism
W230P
-
exhibits properties similar to the parent enzyme with regard to steroid specificities and kinetics toward substrates
Y172A
Km value for 9,10-phenanthrenequinone (model substrate) is 12.5 times higher than that for the wild-type enzyme
C227S
displays a similar kcat, but a 30fold higher Km value for S-nitrosoglutathione, and does not show substrate inhibition
