Gene namei

  • Name:glpB

Pathwayi

  • Pathwayi: glycerol degradation via glycerol kinase pathway

    This protein is involved in step 1 of the subpathway that synthesizes glycerone phosphate from sn-glycerol 3-phosphate (anaerobic route). This subpathway is part of the pathway glycerol degradation via glycerol kinase pathway, which is itself part of Polyol metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes glycerone phosphate from sn-glycerol 3-phosphate (anaerobic route), the pathway glycerol degradation via glycerol kinase pathway and in Polyol metabolism.

Catalytic activityi

  • sn-glycerol 3-phosphate + a quinone = glycerone phosphate + a quinol.

Sequence similaritiesi

Subunit structurei

  • Composed of a catalytic GlpA/B dimer and of membrane bound GlpC.

Functioni

  • Conversion of glycerol 3-phosphate to dihydroxyacetone. Uses fumarate or nitrate as electron acceptor.
