Comments [?]

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.
case <OS:Enterobacteria phage T4>
Subunit Monomer. Interacts with the baseplate central spike protein Gp5; this interaction selectively inhibits the lysozyme activity of the baseplate central spike protein.
else
Subunit Monomer. Interacts with the baseplate central spike protein; this interaction selectively inhibits the lysozyme activity of the baseplate central spike protein.
end case
Subcellular location Host periplasm.
Similarity Belongs to the Tevenvirinae spackle protein family.
