<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Involved in the biosynthesis of C(50) beta-cyclic carotenoids (PubMed:17008032).

The elongase/hydratase domain catalyzes the elongation of lycopene by attaching a C5 isoprene unit at C-2, as well as the hydroxylation of the previous end of the molecule (By similarity).

The enzyme acts at both ends of the substrate, and catalyzes the conversion of lycopene to the C(45) intermediate dihydroisopentenyldehydrorhodopin (DH-IDR) and the conversion of isopentenyldehydrorhodopin (IDR) to the C(50) carotenoid dihydrobisanhydrobacterioruberin (DH-BABR) (By similarity).

The beta-cyclase domain may produce the C(50) beta-cyclic carotenoid C.p.450 from the C(50) carotenoid dihydrobisanhydrobacterioruberin (DH-BABR) (Probable).

<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:iE20A54C34CD3A406
