Abstract
Bacteria have devised sophisticated His-Asp phosphorelay signaling systems for eliciting a variety of adaptive responses to their environment. The histidine-containing phosphotransfer (HPt) domain, found in many signal transduction protein, functions as a mediator of the His-Asp phosphorelay. The ArcB anaerobic sensor of E. coli contains such a HPt domain, although its function is not fully understood. In this study, we provide in vivo and in vitro evidence that the HPt domain is capable of interacting with the CheY receiver, which contains a phospho-accepting aspartate residue.
