additional information studies on mGDH mutants with substitutions for amino acid residues around pyrroloquinoline quinone show that Asp-466 and Lys-493, which are crucial for catalytic activity, interact with bound ubiquinone. It is proposed that the bound ubiquinone is involved in the catalytic reaction in addition to the intramolecular electron transfer in mGDH Escherichia coli

physiological function pulse radiolysis analysis reveal that the bound ubiquinone exists very close to pyrroloquinoline quinone at a distance of 11-13 A. Studies on mGDH mutants with substitutions for amino acid residues around pyrroloquinoline quinone show that Asp-466 and Lys-493, which are crucial for catalytic activity, interact with bound ubiquinone. It is proposed that the bound ubiquinone is involved in the catalytic reaction in addition to the intramolecular electron transfer in mGDH Escherichia coli
