C274 (= C274) binding Zn(2+); mutation to A: Zinc ion is no longer a tight-binding inhibitor and does not promote isomerization.
CL 274:275 (= CL 274:275) binding carbamoyl phosphate
R320 (= R319) binding carbamoyl phosphate; mutation to A: Much less active than the wild-type.
A326 (= A325) mutation to G: Activity greater than the wild-type and Km for ornithwinas increases about twofold.
