ECMDB

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.
