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. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

Catalyzes the NADPH-dependent reduction of L-xylulose, D-xylulose, L-+ erythrulose, D-erythrose, D-threose, L-ribulose, 1,4-dibromo-2,3-butanedione and 2,3-heptanedione (PubMed:21477590).

Also active against isatin, 9,10-phenanthrenequinone, menadione, 2,3-hexaenadione and 3,4-hexahenadione (PubMed:21300042).

No activity observed when tested using NADH rather than NADPH (PubMed:21300042).

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