Web4 nov. 2011 · To determine the mechanism of action, we collected LDH-A and -B inhibition data in competition reactions with pyruvate or NADH and evaluated the results using software for enzyme kinetics analysis. We found that galloflavin inhibits both human LDH isoforms by preferentially binding the free enzyme, without competing with the substrate … WebKanno et al. (1980) described a family with deficiency of the muscle (M) isoform of LDH (LDHA). The proband was an 18-year-old male who complained of exertional myoglobinuria and easy fatigue. Ischemic work of the forearm was accompanied by increased blood lactate, pyruvate, and serum creatine kinase, with myoglobinuria.
