Protein
Glycerol-1-phosphate dehydrogenase [NAD(P)+]
Organism
Methanothermobacter thermautotrophicus (strain ATCC 29096 / DSM 1053 / JCM 10044 / NBRC 100330 / Delta H)
Function
Catalyzes the NAD(P)H-dependent reduction of dihydroxyacetonephosphate (DHAP or glycerone phosphate) to glycerol 1-phosphate (G1P). The G1P thus generated is used as the glycerophosphate backbone of phospholipids in the cellular membranes of Archaea. Is also able to catalyze the reverse reaction, i.e. the NAD(P)(+)-dependent oxidation of G1P but not of G3P. Is not active toward glycerol, dihydroxyacetone, glyceraldehyde-3-phosphate, glyceraldehyde and glycerol-2-phosphate.
Similarity
Belongs to the glycerol-1-phosphate dehydrogenase family.
