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>

Catalyzes the hydrolitical oxidation of 1,3,7-trimethylxanthine (caffeine) by incorporation of an oxygen atom originating from a water molecule into position C-8 to produce 1,3,7-trimethyluric acid (TMU). Coenzyme Q0 is the preferred electron acceptor and coenzyme Q2 can also be used, but oxygen and NADP cannot.1 Publication

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