Function

function

Inhibits viral DNA ejection into the host cytoplasm, thereby confering the infected host bacteria with immunity against secondary phage infection. Achieves superinfection exclusion by localizing to the periplasm and inhibiting the activity of tail-associated lysozyme, thereby preventing penetration by the tail tube of incoming phages.
