Protein attributes

Sequence length	419 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Conversion of glycerol 3-phosphate to dihydroxyacetone. Uses fumarate or nitrate as electron acceptor By similarity. HAMAP-Rule MF_00753
Catalytic activity	sn-glycerol 3-phosphate + a quinone = glycerone phosphate + a quinol. HAMAP-Rule MF_00753
Cofactor	FMN By similarity.
Pathway	Polyol metabolism; glycerol degradation via glycerol kinase pathway; glycerone phosphate from sn-glycerol 3-phosphate (anaerobic route): step 1/1. HAMAP-Rule MF_00753
Subunit structure	Composed of a catalytic GlpA/B dimer and of membrane bound GlpC By similarity.
Subcellular location	Cell inner membrane; Peripheral membrane protein By similarity. Note: Loosely bound to the cytoplasmic membrane often occurring in vesicles associated with fumarate reductase By similarity. HAMAP-Rule MF_00753
Sequence similarities	Belongs to the anaerobic G-3-P dehydrogenase subunit B family.
