Conserved membrane protein YwbH; Increases the activity of extracellular murein hydrolases possibly by mediating their export via hole formation. Inhibited by the antiholin-like proteins LrgAB. In an unstressed cell, the LrgAB products probably inhibit the function of the CidA protein. When a cell is stressed by the addition of antibiotics or by other factors in the environment, CidA possibly oligomerizes within the bacterial cell membrane, creating lesions that disrupt the proton motive force, which in turn results in loss of cell viability. These lesions are also hypothesized to regu [...]
