Conformational transitions of adenylate kinase: switching by cracking.
Conformational heterogeneity in proteins is known to often be the key to their function. We present a coarse grained model to explore the interplay between protein structure, folding and function which is applicable to allosteric or non-allosteric proteins. We employ the model to study the detailed mechanism of the reversible conformational transition of Adenylate Kinase (AKE) between the open ...
متن کاملConformational Transitions in Adenylate Kinase
Large conformational changes in the LID and NMP domains of adenylate kinase (AKE) are known to be key to ligand binding and catalysis, yet the order of binding events anddomainmotion is not well understood. Combining the multiple available structures for AKEwith the energy landscape theory for protein folding, a theoretical model was developed for allostery, order of binding events, and efficie...

متن کاملLarge-scale allosteric conformational transitions of adenylate kinase appear to involve a population-shift mechanism.
Large-scale conformational changes in proteins are often associated with the binding of a substrate. Because conformational changes may be related to the function of an enzyme, understanding the kinetics and energetics of these motions is very important. We have delineated the atomically detailed conformational transition pathway of the phosphotransferase enzyme adenylate kinase (AdK) in the ab...
متن کاملMapping the Dynamics Landscape of Conformational Transitions in Enzyme: The Adenylate Kinase Case.
Conformational transition describes the essential dynamics and mechanism of enzymes in pursuing their various functions. The fundamental and practical challenge to researchers is to quantitatively describe the roles of large-scale dynamic transitions for regulating the catalytic processes. In this study, we tackled this challenge by exploring the pathways and free energy landscape of conformati...
