Malonamoyl-CoA synthetase; part of the gene cluster that mediates the biosynthesis of viridicatumtoxin, a tetracycline-like fungal meroterpenoid with a unique, fused spirobicyclic ring system (PubMed:20534346).

The first step of the pathway is the production of the malonamoyl-CoA starter unit for the polyketide synthase vrtA (PubMed:20534346).

The aldolase vrtJ may be involved in the synthesis of the malonamate substrate for malonamoyl-CoA synthetase vrtB (PubMed:20534346).

The polyketide synthase vrtA then may utilize the malonamoyl-CoA starter unit, followed by sequential condensation of eight malonyl-CoA units to form the polyketide backbone (PubMed:20534346).

The cyclization of the last ring could be mediated by the lactamase-like protein vrtG (PubMed:20534346).

The proposed post-PKS tailoring steps are an hydroxylation at C5 catalyzed the cytochrome P450 monooxygenase vrtE, a hydroxylation at C12a catalyzed by VrtH and/or VrtI, and an O-methylation by the O-methyltransferase vrtF (PubMed:20534346, PubMed:24161266).

VrtC is then proposed to catalyze the transfer of a geranyl group synthesized by vrtD to the aromatic C ring of the tetracyclic polyketide intermediate of viridicatumtoxin to yield previridicatumtoxin (PubMed:20534346).

Finally, the cytochrome P450 monooxygenase vrtK catalyzes the spirocyclization of the geranyl moiety of previridicatumtoxin to afford viridicatumtoxin (PubMed:24161266).

<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:i510556E849FE3D8C
