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>

<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

Membrane-anchoring subunit of succinate dehydrogenase 2 (Sdh2). Sdh2 may catalyze the two-electron oxidation of succinate to fumarate with a corresponding reduction of quinone to quinol under low oxygen conditions, when the primary aerobic succinate dehydrogenase (Sdh1) is inhibited. Sdh2 seems to be the generator of the proton motive force (PMF) under hypoxia.1 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. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

Cells lacking the sdh2 operon (sdhCDAB) display a stationary phase exit defect after 60 days in culture. They show only slight difference in intracellular succinate and malate concentrations during aerobic growth or hypoxia when compared to wild-type. The mutant strain is more susceptible to proton motive force (PMF) inhibition than the parental strain, and it was impossible to recover colonies from mutant cultures after 21 days. Cells harboring a deletion of sdh2 consume oxygen at a reduced rate and are able to modulate respiration as dissolved oxygen (DO) is depleted to about 6%.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:iAB3FF1D5466B8813
