This protein is involved in step 1 of the subpathway that synthesizes N(2)-acetyl-L-ornithine from L-glutamate.1 Publication
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Amino-acid acetyltransferase (argA), Amino-acid acetyltransferase (argA)
  2. Acetylglutamate kinase (argB), Acetylglutamate kinase (argB)
  3. N-acetyl-gamma-glutamyl-phosphate reductase (argC), N-acetyl-gamma-glutamyl-phosphate reductase (argC)
  4. Acetylornithine/succinyldiaminopimelate aminotransferase (argD), Acetylornithine/succinyldiaminopimelate 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. 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:iAE0D84902456797A
