FAD-dependent glycerol-3-phosphate dehydrogenase (EC 22.214.171.124) (GPD) catalyzes the conversion of glycerol-3-phosphate into dihydroxyacetone phosphate. In bacteria  it is associated with the utilization of glycerol coupled to respiration. In Escherichia coli, two isozymes are known: one expressed under anaerobic conditions (gene glpA) and one in aerobic conditions (gene glpD). In eukaryotes, a mitochondrial form of GPD participates in the glycerol phosphate shuttle in conjunction with an NAD-dependent cytoplasmic GPD (EC 126.96.36.199) [2,3].
These enzymes are proteins of about 60 to 70 Kd which contain a probable FAD-binding domain in their N-terminal extremity. The mammalian enzyme differs from the bacterial or yeast proteins by having an EF-hand calcium-binding region (See <PDOC00018>) in its C-terminal extremity.
We developed two signature patterns. One based on the first half of the FAD-binding domain and one which corresponds to a conserved region in the central part of these enzymes.Expert(s) to contact by email:
