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.

Catalyzes the methylation of C-11 in precorrin-4 to form precorrin-5.

Caution

Was originally thought to originate from Pseudomonas denitrificans, but similarity searches show that the sequence is much closer to Sinorhizobium. The entry's taxonomy has been changed.Curated

This protein is involved in step 4 of the subpathway that synthesizes cob(II)yrinate a,c-diamide from precorrin-2 (aerobic route).
Proteins known to be involved in the 10 steps of the subpathway in this organism are:
  1. Precorrin-2 C(20)-methyltransferase (cobI)
  2. Precorrin-3B synthase (cobG)
  3. Precorrin-3B C(17)-methyltransferase (cobJ)
  4. Precorrin-4 C(11)-methyltransferase (cobM)
  5. Precorrin-6A synthase [deacetylating] (cobF)
  6. Precorrin-6A reductase (cobK)
  7. Precorrin-6Y C(5,15)-methyltransferase [decarboxylating] (cobL)
  8. Precorrin-8X methylmutase (cobH)
  9. Hydrogenobyrinate a,c-diamide synthase (cobB)
  10. Aerobic cobaltochelatase subunit CobT (cobT), Aerobic cobaltochelatase subunit CobS (cobS), Aerobic cobaltochelatase subunit CobN (cobN)
This subpathway is part of the pathway adenosylcobalamin biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes cob(II)yrinate a,c-diamide from precorrin-2 (aerobic route), the pathway adenosylcobalamin biosynthesis and in Cofactor biosynthesis.

<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:i50F5E6F5F67FF733
