LITERATURE
IMAGE
EDTA
-
75% inhibition at 1 mM, complete inhibition at 2 mM, reversible by Zn2+ addition, competitive versus Zn2+, kinetics, overview
imidazole
-
the demethylation of cob(I)inamide reaction is inhibited by imidazole. Imidazole does not inhibit methyltransfer from methylcob(III)alamin to coenzyme M at 10 mM
additional information
-
1 mm nitrilotriacetic acid has almost no effect on the MtaA activity
