Glucose 6-Phosphate Dehydrogenase from Human Erythrocytes

On the Chemistry of Rabbit Muscle α-Glycerophosphate Dehydrogenase*

“…The nature of agents and conditions which dissociate the protein are fairly standard, since acid and alkali are now well-recognized means for the demonstration of subunits. Freezing as a cause of dissociation has also been observed for glucose-6-phosphate dehydrogenase (Kirkman and Hendrickson, 1962). But the subunits must be held together with extreme tenacity in a-glycerophosphate dehydrogenase, since reactivation occurs at extraordinarily high dilution.…”

Induction of Polymer Formation in Solutions of Bovine Pancreas Carboxypeptidase A by Aromatic Compounds*

“…This temperature dependence is that predicted for structures stabilized by hydrophobic bonds (Kauzmann, 1959;Némethy and Scheraga, 1962) and is one of the most dramatic physical manifestations of this type of bonding. Even though the nature of this temperature dependence for hydrophobic bonding is well understood from model systems, the experimental demonstration of its occurrence in protein-protein interaction is still scant (Murayama, 1956;Lauffer et al, 1958;Kirkman and Hendrickson, 1962;Von Eys et al, 1964). Hence, the present data constitute significant confirmation of the existence of these forces in a protein system.…”

Regulation and kinetics of glucose 6-phosphate dehydrogenase from Candida utilis

“…It is not unlikely that both the absolute concentration of NADP+ and NADPH and the ratio of their levels might be important for regulation. While ATP severely inc V*_Tlucose-6-phosphate dehydrogenase (glucose 6-phosphate:NADP oxidoreductase, EC 1.1.1.49)* 1 **is an enzyme which has been highly purified and extensively studied from many sources including microorganisms and mammalian tissues (Glaser and Brown, 1955;Noltmann et al, 1961;Marks et al, 1961;Kirkman and Hendrickson, 1962; Chung and Langdon 1963;Yoshida, 1966; Afolayan, 1968, 1971; Afolayan, 1969;Afolayan and Luzzatto, 1971; Sanwal, 1970;Olive et al, 1971).
