Annotation score:3 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 transcript leveli <p>This indicates the type of evidence that supports the existence of the protein.

Energy-dependent efflux pump that contributes to drug resistance (PubMed:8682782, PubMed:11094273, PubMed:15215089, PubMed:21332993).

Catalyzes the efflux of norfloxacin and several related fluoroquinolones (FQ) (PubMed:8682782).

Contributes significantly to the intrinsic MICs for ethidium bromide and acriflavine (PubMed:11094273, PubMed:21332993).

Overexpression confers low-level resistance to hydrophilic FQ such as ciprofloxacin, ofloxacin and levofloxacin, and to ethidium bromide, acridine, acriflavine, rhodamine 123 and some quaternary ammonium compounds (PubMed:8552639, PubMed:11094273).

May contribute to resistance to certain beta-lactams (PubMed:15215089).

Probably uses the proton motive force (PubMed:8682782).

<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.
