Role of the essential thiol groups of yeast alcohol dehydrogenase.
1. Yeast alcohol dehydrogenase inactivated by reaction with iodoacetamide retains 85% of the original NADH-binding capacity as measured under conditions of saturating coenzyme concentration. 2. The dissociation constant of the enzyme-NADH complex is unaffected by inactivation of the enzyme with iodoacetamide, and the affinity of the enzyme for NAD(+) and pyridine-3-aldehyde-adenine dinucleotide...
متن کاملActivators of yeast hexokinase.
The rate of the ATP:glucose transphosphorylase reaction catalyzed by yeast hexokinase, isozyme PII, is inhibited by lowering the pH of the reaction below 7.0, especially at suboptimal concentrations of ATP. This effect of acidity is largely overcome by activators such as orthophosphate, citrate, malate, 3-phosphoglycerate, and riboside triphosphates. Thus, in the acid range, ATP appears to serv...

متن کاملActivation of Yeast Hexokinase PI1
Activation of yeast hexokinase PI1 at low pH by citrate or ATP has been shown to occur at the monomer level, without requiring association to the dimer level. Thus, the previous suggestion (Steitz, T. A., Anderson, W. F., Fletterick, R. G., and Anderson, C. M. (1977) J. Biol. Chem. 252, 4494-4500) that anionic activators of hexokinase, such as citrate and ATP, act by binding to the intersubunit...
