Protein

p-aminobenzoyl-glutamate transport protein

Gene

abgT

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score:

Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>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

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
