CC   -!- FUNCTION: Inhibits viral DNA ejection into the host cytoplasm, thereby
CC       confering the infected host bacteria with immunity against secondary
CC       phage infection. Achieves superinfection exclusion by localizing to the
CC       periplasm and inhibiting the activity of tail-associated lysozyme,
CC       thereby preventing penetration by the tail tube of incoming phages.
case <OS:Enterobacteria phage T4>
CC   -!- SUBUNIT: Monomer. Interacts with the baseplate central spike protein
CC       Gp5; this interaction selectively inhibits the lysozyme activity of the
CC       baseplate central spike protein.

CC   -!- SUBCELLULAR LOCATION: Host periplasm.
CC   -!- SIMILARITY: Belongs to the Tevenvirinae spackle protein family.
