Britain State and Accessibility of Zinc in Yeast Alcohol Dehydrogenase

1. Yeast alcohol dehydrogenase (EC 1.1.1.1) is inhibited in the presence of 1,10-phenanthroline. 2. A conformational change in the enzyme's structure is induced by 1,1I0-phenanthroline, and is abolished in the presence of NADH. 1,10-Phenanthroline binds to the enzyme competitively with respect to NADH, with a stoicheiometry of 2mol of 1,10phenanthroline/144… CONTINUE READING
