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

Essential subunit of the protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation. Overexpression of some hybrid proteins has been thought to jam the protein secretion apparatus resulting in cell death; while this may be true it also results in FtsH-mediated degradation of SecY.1 Publication

Part of the essential Sec protein translocation complex which comprises SecA, SecYEG and auxiliary proteins SecDF-YajC and YidC/OxaA. Heterotrimer consisting of SecY, SecE and SecG subunits. The SecDF-YidC-YajC translocase forms a supercomplex with SecYEG, called the holo-translocon (HTL) (PubMed:27435098). The stoichiometry of the super complex may be SecYEG:YidC:SecDF 4:3:1, YajC is in the reconstituted complex (with SecDF) but as no antibody is available it could not be quantified (PubMed:27435098). The heterotrimers can form oligomers, although 1 heterotrimer is thought to be able to translocate proteins. The channel interacts with SecA via subunit SecY. SecE might contact ribosomal protein L23 and/or L29 when the translocation complex is docked with the ribosome.

<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:i94D37280522875CE
