Intramembrane helix-helix interactions as the basis of inhibition of the colicin E1 ion channel by its immunity protein.

The Journal of biological chemistry - 15 May 1993

Zhang Y L, Cramer W A

Abstract excerpt

It had previously been hypothesized that the ability of a small number of immunity protein molecules in the cytoplasmic membrane to confer protection against the lethal effects of a channel-forming colicin involves a complex stabilized by electrostatic or polar interactions between immunity protein, the colicin channel, and specific sites on the cytoplasmic membrane surface defined by the presence of the tol gene...
