Protein attributes

Sequence length	542 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Conversion of glycerol 3-phosphate to dihydroxyacetone. Uses fumarate or nitrate as electron acceptor.
Catalytic activity	sn-glycerol 3-phosphate + a quinone = glycerone phosphate + a quinol.
Cofactor	FAD. FMN.
Pathway	Polyol metabolism; glycerol degradation via glycerol kinase pathway; glycerone phosphate from sn-glycerol 3-phosphate (anaerobic route): step 1/1.
Subunit structure	Composed of a catalytic glpA/B dimer and of membrane bound glpC.
Subcellular location	Cell inner membrane; Peripheral membrane protein. Note: Loosely bound to the cytoplasmic membrane often occurring in vesicles associated with fumarate reductase.
Sequence similarities	Belongs to the FAD-dependent glycerol-3-phosphate dehydrogenase family.
