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. HAMAP-Rule MF_00753

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. 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.
