Comments
This enzyme belongs to the superfamily of NAD(P)H-dependent shikimate dehydrogenase. This superfamily had been previously subdivided into four groups (1) AroE, EC=1.1.1.25, Shikimate dehydrogenases; (2) YdiB, EC=1.1.1.282, Shikimate/quinate dehydrogenases; (3) SdhL;EC=1.1.1.25, Shikimate dehydrogenase-like protein; (4) RifI, EC=1.1.1.25, Shikimate dehydrogenase (literature [12]).
This enzyme corresponds to YdiB, which is a bifunctional enzyme that can catalyze the reversible reduction to produce both quinate and shikimate.
Although this enzyme was proposed to have different catalytic mechanism from that of its homologue, AroE (D00845 in EzCatDB), according to the literature [2] and [5], it has a similar active site, suggesting that it must have the same catalytic mechanism as that of its homologue. Thus, the catalytic mechanism of this enzyme has been categorized in the same group with the homologous enzyme (D00845).
