3.5.1.16
H355A
site-directed mutagenesis, the mutation affects a key aspect of the active site of the enzyme, i.e. metal cofactor binding. The mutant contains no Zn2+ ions but requires Zn2+ for activity, decrease in activity of H355A due to a 380fold decrease in kcat. The catalytic efficiency for the Co(II)-loaded H355A mutant enzyme is about 160fold less than the Co(II)-loaded wild-type enzyme
