Annotation score:4 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.

Component of the F(420)H2 dehydrogenase (FPO complex) which is part of the energy-conserving F(420)H2:heterodisulfide oxidoreductase system. The membrane-bound electron transfer system of the complex plays an important role in the metabolism of methylotrophic methanogens when the organisms grow on methanol or methylamines. Catalyzes the oxidation of methanophenazine to dihydromethanophenazine. It shuttles electrons from F(420)H2, via FAD and iron-sulfur (Fe-S) centers, to methanophenazine (an electron carrier in the membrane). It couples the redox reaction to proton translocation (for every two electrons transferred, two hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. It also catalyzes the oxidation of F(420)H2 with quinones such as 2,3-dimethyl-1,4-naphthoquinone, 2-methyl-1,4-naphthoquinone and tetramethyl-p-benzoquinone.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:i97C19D7AF597CE99
