This protein is involved in step 4 of the subpathway that synthesizes (S)-reticuline from (S)-norcoclaurine.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. (RS)-norcoclaurine 6-O-methyltransferase (6OMT)
  2. (S)-coclaurine N-methyltransferase (CNMT)
  3. (S)-N-methylcoclaurine 3'-hydroxylase isozyme 1 (CYP80B3)
  4. 3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase 1 (4'OMT1), 3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase 2 (4'OMT2)
This subpathway is part of the pathway (S)-reticuline biosynthesis, which is itself part of Alkaloid 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:i9464FC9A537835EB
