Identification and Characterization of a Putative Chemotaxis Protein, CheY, from the Oral Pathogen Campylobacter rectus.
Campylobacter rectus is an understudied oral bacterium that contributes to periodontitis. Processes that contribute to the disease-causing capabilities of pathogens, such as chemotaxis, are largely unknown in C. rectus. The aim of this study was to better understand C. rectus chemotaxis, by examining the C. rectus genome for the presence of a cheY gene. CheY proteins play a part in chemotaxis by acting as two-component response regulators. Significantly, CheY proteins from several pathogens, including the related species Campylobacter jejuni, have been shown to contribute to bacterial virulence. Degenerate PCR, RT-PCR, sequence analyses, and structural modeling showed that C. rectus encodes a gene (Cr-CheY) which shares significant homology with previously characterized CheY proteins. Functional studies of a recombinant form of the protein supports a likely role of Cr-CheY in C. rectus chemotaxis. Cr-CheY is the first CheY characterized from the oral campylobacters.
