CHEY FROM THERMOTOGA MARITIMA (APO-II)
Overview
The crystal structure of CheY protein from Thermotoga maritima has been, determined in four crystal forms with and without Mg++ bound, at up to 1.9, A resolution. Structural comparisons with CheY from Escherichia coli shows, substantial similarity in their folds, with some concerted changes, propagating away from the active site that suggest how phosphorylated, CheY, a signal transduction protein in bacterial chemotaxis, is recognized, by its targets. A highly conserved segment of the protein (the "y-turn, loop," residues 55-61), previously suggested to be a rigid recognition, determinant, is for the first time seen in two alternative conformations, in the different crystal structures. Although CheY from Thermotoga has, much higher thermal stability than its mesophilic counterparts, ... [(full description)]
