Protein

S-(2-succino)cysteine N-acetyltransferase

Gene

scmL

Organism
Bacillus subtilis (strain 168)
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.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Catalyzes the N-acetylation of S-(2-succino)cysteine. Is involved in a S-(2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine. Moreover, 2SC is a toxic compound in B.subtilis at high exogenous concentrations, and this enzyme relieves 2SC toxicity via N-acetylation.1 Publication

Miscellaneous

Fumarate mediated succination of thiols increases in certain tumors and in response to glucotoxicity associated with diabetes. Therefore, S-(2-succino)-adducts such as S-(2-succino)cysteine (2SC) are considered oncometabolites and biomarkers for human disease. The demonstration of a metabolic disposal route for a S-(2-succino)-compound paves the way toward the identification of corresponding pathways in other species.1 Publication

    Cells lacking this gene almost lose the ability to grow on 2SC as the sulfur source but are still able to grow on sulfate. Moreover, in contrast to wild type, they highly accumulate 2SC when grown on fumarate as the sulfur source. Addition of 2SC causes growth inhibition of the deletion mutant but not the wild type grown on sulfate as the sulfur source.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:iB5594F5D7D143476
