Annotation score:3 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>

4-dimethylallyltryptophan N-methyltransferase; part of the gene cluster that mediates the biosynthesis of isofumigaclavines, fungal ergot alkaloids (PubMed:28620689). The tryptophan dimethylallyltransferase ifgA catalyzes the first step of ergot alkaloid biosynthesis by condensing dimethylallyl diphosphate (DMAP) and tryptophan to form 4-dimethylallyl-L-tryptophan (PubMed:28620689). The second step is catalyzed by the methyltransferase ifgB that methylates 4-dimethylallyl-L-tryptophan in the presence of S-adenosyl-L-methionine, resulting in the formation of N-methyl-dimethylallyl-L-tryptophan (PubMed:28620689). The catalase ifgD and the FAD-dependent oxidoreductase ifgC then transform N-methyl-dimethylallyl-L-tryptophan to chanoclavine-I which is further oxidized by ifgE in the presence of NAD+, resulting in the formation of chanoclavine-I aldehyde (PubMed:28902217). The chanoclavine-I aldehyde reductases ifgG and/or fgaOx3 reduce chanoclavine-I aldehyde to dihydrochanoclavine-I aldehyde that spontaneously dehydrates to form 6,8-dimethyl-6,7-didehydroergoline (PubMed:28620689, PubMed:28902217). The festuclavine dehydrogenases ifgF1 and/or ifgF2 then catalyze the reduction of 6,8-dimethyl-6,7-didehydroergoline to form festuclavine (PubMed:28620689). Hydrolysis of festuclavine by a yet undetermined cytochrome P450 monooxygenase (called ifgH) then leads to the formation of isofumigaclavine B which is in turn acetylated by ifgI to isofumigaclavine A (PubMed:28620689). Penicillium roqueforti has interestingly at least two sets of genes for the consumption of chanoclavine-I aldehyde on three different loci, the OYEs ifgG/fgaOx3 and the festuclavine synthase homologs ifgF1/ifgF2 (PubMed:28620689, PubMed:28902217). The reason for the duplication of these genes is unclear, probably to ensure the conversion of chanoclavine-I aldehyde by differential gene expression under various environmental conditions (PubMed:28902217).2 Publications

<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:i6C47190C75C1D5C0
