Annotation score:5 out of 5

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

No difference in growth at 37 or 15 degrees Celsius (PubMed:16352840), decreased growth at 16 degrees Celsius (PubMed:23175651). The presence of CshA or CshB is essential for viability; in a cshA disruption mutant further depletion of cshB stops growth after 1 cell duplication (PubMed:16352840). Others show a quadruple disruption of all RNA helicases (cshA, cshB, deaD, yfmL) was not lethal at 37 degrees Celsius, although both 50S and 70S ribosomes are decreased, but growth stops at 16 degrees (PubMed:23175651). A double cshB-cspB disruption mutant cannot be made. A double cshB-cspD mutant grows slowly at 15 degrees Celsius (PubMed:16352840). Decreased amounts of 70S ribosomes (PubMed:23175651).2 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:iB6D425EF6D433789
