COMMENTARY 
LITERATURE
E381A
the mutation mimics the active site composition of naturally occurring isozymes CKO4/6 and CKO2/3
E381S
the mutation mimics the active site composition of naturally occurring isozymes CKO4/6 and CKO2/3
L492A
the mutant retains an unchanged pattern of selectivity to variously substituted ureas but it is much more susceptible to the inhibition by phenylureas as IC50 values are 10-50times lower than those for wild type enzyme
