Comments [?]

case <OC:Bacteria>
Function Conversion of glycerol 3-phosphate to dihydroxyacetone. Uses fumarate or nitrate as electron acceptor.
end case
Catalytic activity RHEA:18977: a quinone + sn-glycerol 3-phosphate = a quinol + dihydroxyacetone phosphate
EC 1.1.5.3
Cofactor FMN
Pathway Polyol metabolism; glycerol degradation via glycerol kinase pathway; glycerone phosphate from sn-glycerol 3-phosphate (anaerobic route): step 1/1.
case <OC:Bacteria>
Subunit Composed of a catalytic GlpA/B dimer and of membrane bound GlpC.
end case
Similarity Belongs to the anaerobic G-3-P dehydrogenase subunit B family.
