Annotation score:5 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>

    This protein is involved in step 1 of the subpathway that synthesizes N(2)-acetyl-L-ornithine from L-glutamate.
    Proteins known to be involved in the 4 steps of the subpathway in this organism are:
    1. Arginine biosynthesis bifunctional protein ArgJ (argJ), Amino-acid acetyltransferase (argA)
    2. Acetylglutamate kinase (argB)
    3. N-acetyl-gamma-glutamyl-phosphate reductase (argC)
    4. Acetylornithine aminotransferase (argD)
    This subpathway is part of the pathway L-arginine 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 N(2)-acetyl-L-ornithine from L-glutamate, the pathway L-arginine 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.
