This sactipeptide undergoes unique processing steps that include proteolytic cleavage after Glu-8, and covalent linkage of the alpha-amino of Asn-9 with the carboxyl of Gly-43 to form a cyclopeptide (PubMed:12696888, PubMed:22366720). Thioether cross-links are formed between cysteines and the alpha-carbons of other amino acids, Cys-12 to Phe-39, Cys-15 to Thr-36, and Cys-21 to Phe-30 (PubMed:12696888, PubMed:22366720). In forming these cross-links, Thr-36 and Phe-39 are converted to D-amino acids (PubMed:12696888). Propeptide cleavage and cyclopeptide formation only occur after all 3 thioether cross-links are formed (PubMed:22366720).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:i055A81DA0D378794
