Antimicrobial activity in the egg wax of the tick Amblyomma hebraeum (Acari: Ixodidae) is associated with free fatty acids C16:1 and C18:2Download
Abstract: Untreated eggs of the tick Amblyomma hebraeum Koch (Acari: Ixodidae) exhibited antimicrobial activity (AMA) against Gram-negative but not Gram-positive bacteria; eggs denuded of wax by solvent extraction showed no AMA. The unfractionated egg wax extract, however, showed AMA against...
Biochemical and structural characterization of CpxP and CpxA, key components of an envelope stress response in Escherichia coliDownload
The Cpx two‐component signal transduction pathway of Escherichia coli consists of an inner membrane‐localized sensor histidine kinase, CpxA, the response regulator, CpxR, and the novel periplasmic accessory protein, CpxP. These proteins mediate a bacterial stress response, sensing envelope...
