Ca2+
10 mM, 24.4% inhibition

10 mM, complete inhibition, reversed by addition of 20 mM 2-mercaptoethanol
hydroquinone
Glu274 is acting as an acidic backbone acceptor residue. Lys262, a basic amino acid from the active site of wheat Hydroquinone glucosyltransferase interacts with the hydroxyl group of hydroquinone and behaves as a side chain donor molecule. Asp264 is also observed as an interacting residue from the active site of hydroquinone glucosyltransferase. It binds to the hydroxyl group of hydroquinone inhibitor and donates hydrogen ion from its side chain group
Mn2+
10 mM, 24.7% inhibition
N-(n-butyl) phosphorothiocic triamide
Glu274 is acting as an acidic backbone donor residue and interacts with the amino group of the inhibitor
phenyl phosphorodiamate
Glu395 is directly interacting with amino group of the inhibitor
Zn2+
10 mM, 87.4% inhibition
