Abstract/OtherAbstract:
Chemical modification of arginine and lysine residues of bovine heart 2-oxoglutarate dehydrogenase with phenylglyoxal and pyridoxal 5'-phosphate inactivated the enzyme, indicating the importance of these residues for the catalysis. Inactivation caused by pyridoxal 5'-phosphate was prevented in the presence of thiamine pyrophosphate and Mg2+ allowing the assumption that lysine residues participate in binding of the cofactor.
