<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>

This protein is involved in step 5 of the subpathway that synthesizes L-threonine from L-aspartate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Aspartokinase (lysC)
  2. no protein annotated in this organism
  3. Homoserine dehydrogenase (hom), Homoserine dehydrogenase (hom)
  4. Homoserine kinase (thrB)
  5. Threonine synthase (thrC)
This subpathway is part of the pathway L-threonine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-threonine from L-aspartate, the pathway L-threonine biosynthesis and in Amino-acid 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.
