CC   -!- FUNCTION: Conversion of glycerol 3-phosphate to dihydroxyacetone.
CC       Uses fumarate or nitrate as electron acceptor (By similarity).
CC   -!- CATALYTIC ACTIVITY: sn-glycerol 3-phosphate + a quinone =
CC       glycerone phosphate + a quinol.
CC   -!- COFACTOR: FMN (By similarity).
CC   -!- PATHWAY: Polyol metabolism; glycerol degradation via glycerol
CC       kinase pathway; glycerone phosphate from sn-glycerol 3-phosphate
CC       (anaerobic route): step 1/1.
CC   -!- SUBUNIT: Composed of a catalytic glpA/B dimer and of membrane
CC       bound glpC (By similarity).
CC   -!- SIMILARITY: Belongs to the anaerobic G-3-P dehydrogenase subunit B
CC       family.
