Cys-15 is oxidized by organic peroxides to cysteine sulfenic acid (Cys-SOH). This can react with the alpha-amido of the following residue to form the sulfenamide cross-link. Oxidation or cross-linking results in the loss of DNA-binding activity and the inactivation of repressor function. Both the cysteine sulfenic acid and the sulfenamide cross-link can react with free cysteine or bacillithiol to form mixed disulfides. Further reduction of OhrR by free sulfhydryl compounds restores repressor activity.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:i4F277EA9AB5EE861
