Annotation score:2 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>

Lactamase-like protein; part of the gene cluster that mediates the biosynthesis of neosartoricin B, a prenylated anthracenone that probably exhibits T-cell antiproliferative activity, suggestive of a physiological role as an immunosuppressive agent (PubMed:23758576). The non-reducing polyketide synthase nscA probably synthesizes and cyclizes the decaketide backbone (By similarity). The hydrolase nscB then mediates the product release through hydrolysis followed by spontaneous decarboxylation (By similarity). The prenyltransferase nscD catalyzes the addition of the dimethylallyl group to the aromatic C5 (By similarity). The FAD-dependent monooxygenase nscC is then responsible for the stereospecific hydroxylation at C2 (By similarity). Neosartoricin B can be converted into two additional compounds neosartoricins C and D (By similarity). Neosartoricin C is a spirocyclic compound that is cyclized through the attack of C3 hydroxyl on C14, followed by dehydration (By similarity). On the other hand, neosartoricin D is a further cyclized compound in which attack of C2 on C14 in neosartoricin C results in the formation of the acetal-containing dioxabicyclo-octanone ring (By similarity). Both of these compounds are novel and possibly represent related metabolites of the gene cluster (By similarity).By similarity1 Publication

<p>This subsection of the 'Function' section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states.

<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:i9BD6B851F1D728BF
