Protein

Toxin RTX-I translocation ATP-binding protein

Gene

apxIB

Organism
Actinobacillus pleuropneumoniae (Haemophilus pleuropneumoniae)
Status
Reviewed-Annotation score:

Annotation score:5 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

Involved in the transport of the toxin RTX-I as well as that of RTX-II.

Miscellaneous

The sequence shown is that of serotype 9.
In strain CM15 (serotype 1), disruption of this gene prevents production of both RTX-I and RTX-II toxin, and no hemolytic activity in mice or pigs.

Caution

Tyr-9 is present instead of the conserved Cys which is expected to be the active site residue of peptidase C39. Thus they are presumed to be without peptidase activity.Curated

<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.
