'''TRANSITION STATE STRUCTURE OF ARGININE KINASE'''<br />

==Overview==

==Transition state structure of arginine kinase==
-
The three-dimensional crystal structure of an arginine kinase, transition-state analogue complex has been refined at 1.2 A resolution, with an overall R factor of 12.3%. The current model provides a unique, opportunity to analyze the structure of a bimolecular (phosphagen kinase), enzyme in its transition state. This atomic resolution structure confirms, in-line transfer of the phosphoryl group and the catalytic importance of, the precise alignment of the substrates. The structure is consistent with, a concerted proton transfer that has been proposed for an unrelated, kinase. Refinement of anisotropic temperature factors and, translation-libration-screw (TLS) analyses led to the identification of, four rigid groups and their prevalent modes of motion in the transition, state. The relative magnitudes of the mobility of rigid groups are, consistent with their proposed roles in catalysis.
