Identification
Name:N-acetylgalactosamine-specific phosphotransferase enzyme IIB component 2
Synonyms:
  • EIIB-Aga'
  • PTS system N-acetylgalactosamine-specific EIIB component 2
Gene Name:agaV
Enzyme Class:
Biological Properties
General Function:Involved in protein-N(PI)-phosphohistidine-sugar phosphotransferase activity
Specific Function:The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in N-acetylgalactosamine transport
Cellular Location:Cytoplasm (Potential)
