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>

Forms membrane-associated dynamic filaments that are essential for cell shape determination (PubMed:11290328, PubMed:19659933). Acts by regulating cell wall synthesis and cell elongation, and thus cell shape (PubMed:19659933). A feedback loop between cell geometry and Mbl localization may maintain elongated cell shape by targeting cell wall growth to regions of negative cell wall curvature (By similarity). Filaments rotate around the cell circumference in concert with the cell wall synthesis enzymes. The process is driven by the cell wall synthesis machinery and does not depend on Mbl polymerization (PubMed:21636745, PubMed:21636744). Organizes peptidoglycan synthesis in the lateral cell wall (PubMed:19659933). Also required for proper chromosome segregation (PubMed:14588250).By similarity5 Publications

Miscellaneous

B.subtilis has three MreB paralogs: MreB, Mbl and MreBH. All paralogs have the ability to support rod-shaped cell growth normal conditions. The multiplicity of paralogs becomes important under stress conditions. They are probably used to allow cells to maintain proper growth and morphogenesis under changing conditions.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. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iD1599B7EEDEAF8A9
