Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Catalyzes the reduction of 5-keto-D-gluconate to D-gluconate, using either NADH or NADPH. Is likely involved in an L-idonate degradation pathway that allows E.coli to utilize L-idonate as the sole carbon and energy source. Is also able to catalyze the reverse reaction in vitro, but the D-gluconate oxidation by the enzyme can only proceed with NAD.1 Publication

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