Gene name

glpB

FUNCTION: Conversion of glycerol 3-phosphate to dihydroxyacetone. Uses fumarate or nitrate as electron acceptor (By similarity).

CATALYTIC ACTIVITY: sn-glycerol 3-phosphate + a quinone = glycerone phosphate + a quinol.

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.

SUBUNIT: Composed of a catalytic glpA/B dimer and of membrane bound glpC (By similarity).

SIMILARITY: Belongs to the anaerobic G-3-P dehydrogenase subunit B family.
