CHEY FROM THERMOTOGA MARITIMA (APO-II)

Structural highlights

2tmy is a 1 chain structure with sequence from Thermotoga maritima. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 2.3Å
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CHEY_THEMA Involved in the transmission of sensory signals from the chemoreceptors to the flagellar motors. CheY seems to regulate the clockwise (CW) rotation (By similarity).

Publication Abstract from PubMed

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, comparison of structural features previously proposed to enhance thermostability such as hydrogen bonds, ion pairs, compactness, and hydrophobic surface burial would not suggest it to be so.

Crystal structures of CheY from Thermotoga maritima do not support conventional explanations for the structural basis of enhanced thermostability.,Usher KC, de la Cruz AF, Dahlquist FW, Swanson RV, Simon MI, Remington SJ Protein Sci. 1998 Feb;7(2):403-12. PMID:9521117^[1]
