Abstract：
:alpha-Glycerophosphate dehydrogenase (EC 1.1.99.5) in mitochondria from liver of the triiodothyronine-treated rats is competitively inhibited by phosphoenolpyruvate, glyceraldehyde 3-phosphate and 3-phosphoglycerate, the apparent Ki values for phosphoenolpyruvate being 0.76 mM at pH 7.0, 1.7 mM at pH 7.4 and 3.5 mM at pH 7.7. The apparent Ki values for glyceraldehyde 3-phosphate and 3-phosphoglycerate are also pH-dependent. Other glycolytic intermediates, such as 2-phosphoglycerate, 2,3-diphosphoglycerate, pyruvate, glucose 6-phosphate, fructose 6-phosphate and fructose 1,6-diphosphate did not alter significantly alpha-glycerophosphate dehydrogenase activity. Palmitoyl-CoA is a competitive inhibitor of this enzyme, with Ki value of about 30 micron.
