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 protein is involved in step 2 of the subpathway that synthesizes pyridoxine 5'-phosphate from D-erythrose 4-phosphate.UniRule annotation1 Publication
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. D-erythrose-4-phosphate dehydrogenase (epd)
  2. Erythronate-4-phosphate dehydrogenase (pdxB)
  3. Phosphoserine aminotransferase (serC)
  4. 4-hydroxythreonine-4-phosphate dehydrogenase (pdxA)
  5. Pyridoxine 5'-phosphate synthase (pdxJ)
This subpathway is part of the pathway pyridoxine 5'-phosphate 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 pyridoxine 5'-phosphate from D-erythrose 4-phosphate, the pathway pyridoxine 5'-phosphate 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.
