- ***************************************************************
-
- FAD-dependent glycerol-3-phosphate dehydrogenase (EC 1.1.99.5) (GPD) catalyzes
- the conversion of glycerol-3-phosphate into dihydroxyacetone phosphate. In
- bacteria [1] 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 it is a mitochondrial enzyme which participates in the glycerol
- phosphate shuttle in conjunction with a NAD-dependent cytoplasmic GPD [2,3].
-
- The enzymes are proteins of about 60 to 70 Kd which contain, in their N-
- terminal extremity, a probable FAD-binding domain. 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.
