LITERATURE
C349S
-
the mutant shows 30% activity compared to the wild type enzyme
C476S
-
the mutant shows 45% activity compared to the wild type enzyme
D75N
-
the mutant shows 288% activity compared to the wild type enzyme
P261S
-
the mutant shows 15% activity compared to the wild type enzyme
R262S
-
the mutant shows 427% activity compared to the wild type enzyme
R269L
-
the mutant shows 232% activity compared to the wild type enzyme
D54N
-
slower reaction than wild type enzyme, higher dissociation constant for binding of phenol than wild type enzyme
P364S
-
only 13% of the FAD is utilized to hydroxylate the substrate phenol, when resorcinol is used as substrate, the reaction is not significantly different from the reaction of the wild type enzyme
R281M
-
slower reaction than wild type enzyme, binds the FAD cofactor more weakly than wild type enzyme
Y298F
-
binds phenol more weakly than wild type enzyme
