Annotation score:5 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>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Involved in the biosynthesis of the riboflavin analog antibiotic roseoflavin (3,8-dimethylamino-riboflavin) (PubMed:27062037).

Catalyzes the site-specific substitution of the C-8 methyl group of riboflavin-5'-phosphate (FMN) by an amino group to yield 8-amino-8-demethylriboflavin 5'-phosphate, via a combined oxidation, decarboxylation and transamination reaction (PubMed:27062037, PubMed:27331868, PubMed:27981706).

The catalysis is initiated by an oxidation step in which the C-8 methyl group on the dimethylbenzene ring of FMN is converted to a formyl group to yield the 8-demethyl-8-formylriboflavin-5'-phosphate (OHC-RP) intermediate (PubMed:27062037).

In the presence of thiamine, the formyl group is oxidized into a carboxyl group to yield the 8-demethyl-8-carboxyriboflavin-5'-phosphate (HO2C-RP) intermediate (PubMed:27062037).

Finally, in the presence of L-glutamate as an amino donor, decarboxylation and aminotransfer occur, resulting in production of 8-demethyl-8-aminoriboflavin-5'-phosphate (PubMed:27062037).

Addition of NAD (but not NADP) to the reaction increases the yield 1.7-fold (PubMed:27062037).

The reaction also proceeds without the addition of any electron acceptor, and it is possible that molecular oxygen serves this role (PubMed:27062037).

<p>The checksum is a form of redundancy check that is calculated from the sequence.
