'''SHIKIMATE KINASE FROM MYCOBACTERIUM TUBERCULOSIS IN COMPLEX WITH ADP, OPEN LID (CONF. B)'''<br />


==Overview==
==Shikimate kinase from Mycobacterium tuberculosis in complex with ADP, open LID (conf. B)==
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 ... [[http://ispc.weizmann.ac.il/pmbin/getpm?17020768 (full description)]]

== Publication Abstract from PubMed ==
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 identified a synergic mechanism by which binding of the first substrate may enhance the affinity for the second substrate.
