SHIKIMATE KINASE FROM MYCOBACTERIUM TUBERCULOSIS IN COMPLEX WITH SHIKIMATE

OverviewOverview

The structural mechanism of the catalytic functioning of shikimate kinase, from Mycobacterium tuberculosis was investigated on the basis of a series, of high-resolution crystal structures corresponding to individual steps in, the enzymatic reaction. The catalytic turnover of shikimate and ATP into, the products shikimate-3-phosphate and ADP, followed by release of ADP, was studied in the crystalline environment. Based on a comparison of the, structural states before initiation of the reaction and immediately after, the catalytic step, we derived a structural model of the transition state, that suggests that phosphoryl transfer proceeds with inversion by an, in-line associative mechanism. The random sequential binding of shikimate, and nucleotides is associated with domain movements. We ... [(full description)]
