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.

Catalyzes the reversible reduction of 2,5-diketo-3-deoxygluconate (DKII or 4,6-dihydroxy-2,5-dioxohexanoate) into 2-keto-3-deoxygluconate (KDG or 2-dehydro-3-deoxygluconate) with a concomitant oxidation of NADH (Ref. 4). To a lesser extent, can also reduce 5-keto-D-gluconate and oxidize D-gluconate and 1,2-propanediol (PubMed:24509771).

Together with KduI, seems to play a role in the catabolism of hexuronates under osmotic stress conditions, substituting for the regular hexuronate degrading enzymes UxaABC and UxuAB whose expression is repressed in these conditions (PubMed:23437267).

In vitro, also exhibits NADH-dependent 20-ketosteroid reductase activity against eukaryotic steroid hormone 11-deoxycorticosterone (11-DOC), which is converted into the product 4-pregnen-20,21-diol-3-one. In addition to 11-DOC, five other C21 steroid compounds (11-deoxycortisol, cortisol, corticosterone, cortisone, and 21-hydroxypregnenolone) are reduced by KduD, but steroids lacking the hydroxyl group at C21 position, such as pregnenolone, testosterone propionate, cortisone acetate, or progesterone, cannot be used as substrate (PubMed:24509771).

Caution

Most strains of E.coli do not exhibit 20-ketosteroid reductase activity against steroid substrates such as 11-DOC, despite containing a full-length kduD gene. This activity is observed in the K12 / DH5-alpha strain, whose disruption of the kdgR gene leads to the constitutive expression of KduD in this strain.1 Publication

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