Protein

p-aminobenzoyl-glutamate transport protein

Gene

abgT

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.2 Publications

Miscellaneous

It is suggested that in wild-type strain abgT would normally be cryptic or not expressed under conditions of growth on minimal medium. Altering the expression of abgT from its wild-type context appears to be the mechanism for obtaining the growth phenotype (PubMed:9829935).1 Publication

Enzyme regulationi

Completely inhibited by 100 nM of sodium azide and slightly inhibited by 100 mM of potassium fluoride.1 Publication
