Comments
This enzyme is composed of N-terminal chorismate mutase domain (EC 5.4.99.5) and C-terminal shikimate dehydrogenase domains (EC 1.1.1.25). Although the tertiary structure of the C-terminal shikimate dehydrogenase domains have been solved, that of the N-terminal domain has not been elucidated.
The C-terminal 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]).
The C-terminal domain corresponds to AroE, which has a similar active site as that of the homologous enzyme (D00845 in EzCatDB). Thus, its catalytic mechanism must be also similar to that of the homologue.
