Application
α-Glycerophosphate Dehydrogenase-Triosephosphate Isomerase from rabbit muscle has been used in spectrophotometric aldolase assay and fructose 2,6 bisphosphate assay. It has also been used in erythrocyte transketolase (ETK) activity to study the prevalence of and factors associated with thiamin deficiency in obese.
α-glycerophosphate dehydrogenase was used in 2-deoxy-ribose 5-phosphate aldolase (DERA) cleavage (retroaldol) assay.
Biochem/physiol Actions
α-Glycerophosphate dehydrogenase (α-GPDH) has the ability to produce reactive oxygen species (ROS), that is induced by Ca2+.
α-glycerophosphate dehydrogenase catalyzes the conversion of dihydroxyacetone to glycerol phosphate. α-Glycerophosphate dehydrogenase (α-GPDH) has the ability to produce reactive oxygen species (ROS), that is induced by Ca2+. Triosephosphate isomerase (TPI) is an essential enzyme in the glycolytic pathway, responsible for converting dihydroxyacetone phosphate (DHAP) into glyceraldehyde-3 phosphate (GAP). TPI′s role is crucial in enhancing the efficiency of the catabolic process within glycolysis. However, a deficiency in TPI can lead to glycolytic enzymopathies, rare genetic disorders characterized by neurologic dysfunction and hemolytic anemia.
General description

1. The fluorescent ATP analogue 1,N6-etheno-ATP is a good substrate and an efficient allosteric inhibitor of rabbit skeletal-muscle phosphofructokinase. 2. Fluorescence energy transfer occurs between bound 1,N6-etheno-ATP and phosphofructokinase. 1,N6-Etheno-ATP fluorescence is enhanced, intrinsic protein fluorescence is quenched, and the

A preparation of phosphofructokinase from rabbit skeletal muscle is described which exploits the association-dissociation properties of the enzyme. Phosphofructokinase to prepared is partially phosphorylated and may be fractioned into three distinct species with sedimentation coefficients of 30 S, 18 S
