title: Antibodies specific for NADPH-binding region of enzymes possessing dehydrogenase activities.
abstract: The results reported in this paper show the presence of a population of antibodies in rabbit polyclonal antiserum that recognize an antigenic site at the NADPH-binding region of enzymes possessing dehydrogenase activities. Antisera from rabbits immunized with glucose-6-phosphate dehydrogenase or fatty acid synthetase were found to inactivate the enzyme dihydrofolate reductase. The inhibitory effect of this site-specific antibody is a time- and concentration-dependent reaction. This immunoinactivation is prevented by preincubation of the enzyme with NADPH.
