These glycerol-1-phosphate dehydrogenase-like proteins have not been characterized. The protein sequences have high similarity with that of glycerol-1-phosphate dehydrogenase (G1PDH) which plays a role in the synthesis of phosphoglycerolipids in Gram-positive bacterial species. It catalyzes the reversibly reduction of dihydroxyacetone phosphate (DHAP) to glycerol-1-phosphate (G1P) in a NADH-dependent manner. Its activity requires Ni++ ion.
