High-resolution structure of shikimate dehydrogenase from Thermotoga maritima reveals a tightly closed conformation.

ABSTRACT: Shikimate dehydrogenase (SDH), which catalyses the NADPH-dependent reduction of 3-dehydroshikimate to shikimate in the shikimate pathway, is an attractive target for the development of herbicides and antimicrobial agents. Structural analysis of a SDH from Thermotoga maritima encoded by the Tm0346 gene was performed to facilitate further structural comparisons between the various shikimate dehydrogenases. The crystal structure of SDH from T. maritima was determined at 1.45 SDH from T. maritima showed a monomeric architecture. The overall structure of SDH from T. maritima comprises the N-terminal α/β sandwich domain for substrate binding and the C-terminal domain for NADP binding. When the T. maritima SDH structure was compared with those of the SDHs from other species, the SDH from T. marit
