Loss of viability. Cells lacking sufficient quantities of this protein undergo morphological changes, namely, swelling and twisting of the cells followed by cell lysis. A polymeric material accumulates at one side of the division septum of the cells and the presence of this material correlates with the bending of the cell. After prolonged depletion in the presence of MgCl2, the cells become very short and fat and eventually spheroidal, but no significant lysis is observed. Addition of sucrose results in rounded cells. Cells are still capable of making division septa. Null mutants show little or no sign of a defined long axis and have a severe shape defect.4 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. 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:iB9984D25BB414A5C
