Overexpression, crystallization and preliminary X-ray crystallographic analysis of shikimate dehydrogenase from Archaeoglobus fulgidus.

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. Previous structural studies have shown that SDH exists in two conformations, an open and a closed form, and it is believed that the conformational state is crucial to understanding its catalytic mechanism. In order to facilitate further structural comparisons among SDHs, including the conformational state, structural analysis of an SDH from Archaeoglobus fulgidus encoded by the Af2327 gene has been initiated. SeMet-labelled SDH from A. fulgidus was overexpressed in Escherichia coli and crystallized at 296 K using ammonium sulfate as a precipitant in order to use the MAD m
