title: D-glyceraldehyde-3-phosphate dehydrogenase from HeLa cells--1. Purification and properties of the enzyme.
abstract: 1. D-GPDH from HeLa cells was isolated and purified. 2. Some basic kinetic constants are reported. 3. Sodium dodecyl polyacrylamide gel electrophoresis gave a single band with a molecular weight of approximately 36 K. 4. ATP and NADH inhibit competitively enzyme activity. 5. Comparative catalytic properties of GPDH from normal and tumor cells were effectuated.
