Taxonomic identifier

349307 [NCBI]

Taxonomic lineage

Archaea › Euryarchaeota › Methanomicrobia › Methanosarcinales › Methanosaetaceae › Methanosaeta

Protein attributes

Sequence length	354 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

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 By similarity.
Catalytic activity	sn-glycerol-1-phosphate + NAD(P)+ = glycerone phosphate + NAD(P)H. HAMAP MF_00497
Cofactor	Binds 1 zinc ion per subunit By similarity.
Pathway	Membrane lipid metabolism; glycerophospholipid metabolism. HAMAP MF_00497
Subcellular location	Cytoplasm Potential.
Sequence similarities	Belongs to the glycerol-1-phosphate dehydrogenase family.
