Annotation score:5 out of 5

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

Catalyzes the reversible reduction of (S)-acetoin to (S,S)-butane-2,3-diol (L-BD) in the presence of NADH. To a lesser extent, can also catalyze the irreversible reduction of diacetyl to (S)-acetoin. Cannot oxidize meso-BD, D-BD, 2-butanol, 1,2-propanediol, ethanol, acetol, 1,2-butanediol, 1,3-butanediol, n-butanol, and n-propanol. Cannot reduce (R)-acetoin, acetol, dihydroxyacetone and 2,4-pentanedione.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:i96A81BD2AE33E55E
