Identification
Name:p-aminobenzoyl-glutamate transport protein
Synonyms:
  • PABA-GLU transport protein
Gene Name:abgT
Enzyme Class:Not Available
Biological Properties
General Function:Not Available
Specific Function:Essential for aminobenzoyl-glutamate utilization. It catalyzes the concentration-dependent uptake of p-aminobenzoyl-glutamate (PABA-GLU) into the cell and allows accumulation of PABA-GLU to a concentration enabling AbgAB to catalyze cleavage into p-aminobenzoate and glutamate. It seems also to increase the sensitivity to low levels of aminobenzoyl-glutamate. May actually serve physiologically as a transporter for some other molecule, perhaps a dipeptide, and that it transports p-aminobenzoyl-glutamate as a secondary activity. The physiological role of abgABT should be clarified. Essential for aminobenzoyl-glutamate utilization.
