Status
Reviewed-Annotation score:

Annotation score:3 out of 5

<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>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

Involved in the modification of secondary bile acids into iso-bile acids (3beta-bile acids) via epimerization of the 3-OH group through a 3-oxo-intermediate. Catalyzes the reduction of 12-alpha-hydroxy-3-oxo-5-beta-cholan-24-oate (3-oxo-DCA) and 3-oxo-5-beta-cholan-24-oate (3-oxo-LCA) to yield isodeoxycholate (isoDCA) and isolithocholate (isoLCA), respectively. Is also able to catalyze the reduction of 3-dehydrocholate (3-oxo-CA or 7alpha,12alpha-dihydroxy-3-oxo-5beta-cholan-24-oate) and 7-alpha-hydroxy-3-oxo-5-beta-cholan-24-oate (3-oxo-CDCA), into isocholate (isoCA) and isochenodeoxycholate (isoCDCA), respectively. Accepts both NADPH and NADH as cosubstrates. The conversion of the abundant bile acid deoxycholate (DCA) into isoDCA by the gut bacterium R.gnavus favors the growth of the keystone commensal genus Bacteroides, since isoDCA is less cytotoxic than its parent compound, DCA; iso-bile acids have thus a potential role in modulating gut community composition.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:i8D2745D901EBCB3D
