Genetic and biochemical analysis of dimer and oligomer interactions of the lambda S holin.

Abstract excerpt

Bacteriophage lambda uses a holin-endolysin system for host cell lysis. R, the endolysin, has muralytic activity. S, the holin, is a small membrane protein that permeabilizes the inner membrane at a precisely scheduled time after infection and allows the endolysin access to its substrate, resulting in host cell lysis. lambda S has a single cysteine at position 51 that can be replaced by a serine without loss of...
