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.

Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released (PubMed:9595661). Plays a role in the regulation of many virulence factors, motility, quorum sensing, mucoidy, a general mechanism for maintaining lytic phage in populations of bacteria, and biofilm formation (PubMed:2152909, PubMed:12644493, PubMed:10792721, PubMed:26633362, PubMed:29760208). Positively controls the T6 secretion system by directly binding to the promoter regions of hcpA and hcpB genes, leading to their expression (PubMed:29760208). Thereby, allows to colonize several hosts efficiently including mammals, insects, nematodes and plants (By similarity) (PubMed:2152909, PubMed:9595661, PubMed:12644493, PubMed:10792721, PubMed:26633362, PubMed:29760208).By similarity6 Publications

Deletion mutants result in reduced production of pyocyanine, motility, and proteolytic activity. The motility defect is due to the inability of these mutants to synthesize flagellin (PubMed:2152909). Significantly decreased porin oprE expression under aerobic conditions (PubMed:9595661). Mutants also show defect in biofilm formation (PubMed:29760208).3 Publications

<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.
