OMPR DNA-BINDING DOMAIN, ESCHERICHIA COLI
Overview
BACKGROUND: The differential expression of the ompF and ompC genes is, regulated by two proteins that belong to the two component family of, signal transduction proteins: the histidine kinase, EnvZ, and the response, regulator, OmpR. OmpR belongs to a subfamily of at least 50 response, regulators with homologous C-terminal DNA-binding domains of approximately, 98 amino acids. Sequence homology with DNA-binding proteins of known, structure cannot be detected, and the lack of structural information has, prevented understanding of many of this familys functional properties., RESULTS: We have determined the crystal structure of the Escherichia coli, OmpR C-terminal domain at 1.95 A resolution. The structure consists of, three alpha helices packed against two antiparallel beta sheets. Two, ... [(full description)]
