Popis: Glyceraldehyde-3-phosphate Dehydrogenase, ATP, Flu­ orescence Glyceraldehyde-3-phosphate dehydrogenase is a gly­colytic enzyme that catalyses conversion of glyceralde-hyde-3-phosphate to 1,3-diphosphoglycerate. ATP has been found to have an inhibitory effect on this enzyme. To establish the interaction between the enzyme and ATP, a fluorescence technique was used. Fluorescence quenching in the presence of ATP suggests cooperative binding of ATP to the enzyme (the Hill obtained coeffi­cient equals 2.78). The interaction between glyceralde-hyde-3-phosphate dehydrogenase and ATP may control not only glycolysis but other activities of this enzyme, such as binding to the cytoskeleton.
