Cofactor	FMN By similarity. HAMAP MF_00753
Pathway	Polyol metabolism; glycerol degradation via glycerol kinase pathway; glycerone phosphate from sn-glycerol 3-phosphate (anaerobic route): step 1/1. HAMAP MF_00753
Subunit structure	Composed of a catalytic glpA/B dimer and of membrane bound glpC By similarity.
Sequence similarities	Belongs to the anaerobic G-3-P dehydrogenase subunit B family.
