<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

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.
