Comments
[?]
| FUNCTION | The actual biological function of YdiB remains unclear, nor is it known whether 3-dehydroshikimate or quinate represents the natural substrate. Catalyzes the reversible NAD-dependent reduction of both 3-dehydroshikimate (DHSA) and 3-dehydroquinate to yield shikimate (SA) and quinate, respectively. It can use both NAD or NADP for catalysis, however it has higher catalytic efficiency with NAD. |
| CATALYTIC ACTIVITY | Reaction=L-quinate + NAD(+) = 3-dehydroquinate + NADH + H(+); Xref=Rhea:RHEA:22364, ChEBI:CHEBI:15378, ChEBI:CHEBI:29751, ChEBI:CHEBI:32364, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.1.1.282; |
| CATALYTIC ACTIVITY | Reaction=L-quinate + NADP(+) = 3-dehydroquinate + NADPH + H(+); Xref=Rhea:RHEA:18425, ChEBI:CHEBI:15378, ChEBI:CHEBI:29751, ChEBI:CHEBI:32364, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.1.1.282; |

| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the shikimate dehydrogenase family. |
