Tailed bacteriophage virions deliver DNA to susceptible cells after adsorbing to specific receptors on the surface of the bacteria. In the Gram-negative bacteria these receptors are surface proteins or polysaccharides. In the phage Sf6-type needle, this distal tip folds into a knob with a TNF-like fold, similar to the fibre knobs of bacteriophage PRD1 and Adenovirus. It contains three bound L-glutamate molecules that are bind tightly in the crevices between the trimers of this trimeric tip [1,2].
