Galactitol-specific phosphotransferase enzyme IIB component (P37188)

Identification
Name:Galactitol-specific phosphotransferase enzyme IIB component
Synonyms:
  • EIIB-Gat
  • PTS system galactitol-specific EIIB component
Gene Name:gatB
Enzyme Class:
Biological Properties
General Function:Involved in sugar:hydrogen symporter activity
Specific Function:The phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane. This system is involved in galactitol transport
Cellular Location:Cytoplasm (Potential)
