    This protein is involved in step 2 of the subpathway that synthesizes L-ectoine from L-aspartate 4-semialdehyde.
    Proteins known to be involved in the 3 steps of the subpathway in this organism are:
    1. Diaminobutyrate--2-oxoglutarate transaminase (ectB)
    2. L-2,4-diaminobutyric acid acetyltransferase (ectA)
    3. L-ectoine synthase (ectC)
    This subpathway is part of the pathway ectoine biosynthesis, which is itself part of Amine and polyamine biosynthesis.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-ectoine from L-aspartate 4-semialdehyde, the pathway ectoine biosynthesis and in Amine and polyamine 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:i088A573FB8EF0424
