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
Research area: Neuroscience
α-Glycerophosphate Dehydrogenase-Triosephosphate isomerase (α-GDH-TPI or GDH/TIM) is an enzyme mixture of α-glycerophosphate dehydrogenase (GDH) and triosephosphate isomerase (TPI).

2-Deoxyribose-5-phosphate aldolase (DERA, EC 4.1.2.4) catalyzes the reversible aldol reaction between acetaldehyde and D-glyceraldehyde-3-phosphate to generate D-2-deoxyribose-5-phosphate. It is unique among the aldolases as it catalyzes the reversible asymmetric aldol addition reaction of two aldehydes. In order to expand the
