CC   -!- FUNCTION: Conversion of glycerol 3-phosphate to dihydroxyacetone. Uses
CC       fumarate or nitrate as electron acceptor. {ECO:0000255|HAMAP-
CC       Rule:MF_00753}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a quinone + sn-glycerol 3-phosphate = a quinol +
CC         dihydroxyacetone phosphate; Xref=Rhea:RHEA:18977, ChEBI:CHEBI:24646,
CC         ChEBI:CHEBI:57597, ChEBI:CHEBI:57642, ChEBI:CHEBI:132124; EC=1.1.5.3;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00753};
CC   -!- COFACTOR:
CC       Name=FMN; Xref=ChEBI:CHEBI:58210;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00753};
CC   -!- PATHWAY: Polyol metabolism; glycerol degradation via glycerol kinase
CC       pathway; glycerone phosphate from sn-glycerol 3-phosphate (anaerobic
CC       route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_00753}.
CC   -!- SUBUNIT: Composed of a catalytic GlpA/B dimer and of membrane bound
CC       GlpC. {ECO:0000255|HAMAP-Rule:MF_00753}.
CC   -!- SIMILARITY: Belongs to the anaerobic G-3-P dehydrogenase subunit B
CC       family. {ECO:0000255|HAMAP-Rule:MF_00753}.
