This is the very C-terminal, chaperone, domain of the bacteriophage protein endosialidase. It releases itself, via the serine-lysine dyad at the N-terminus, from the remainder of the end-tail-spike. Cleavage occurs after the threonine which is the final residue of the End-tail-spike family, Pfam:PF12219. The endosialidase protein forms homotrimeric molecules in bacteriophages [1]. The catalytic dyad allows this portion of the molecule to be cleaved from the more N-terminal region such that the latter can fold and bind to polysialic acid in the bacterial outer envelope [1].

phage tail spike protein

This HMM represents the conserved N-terminal region, typically from about residue 25 to about residue 350, of a family of uncharacterized phage proteins 500 to 1700 residues in length. Member protein Gp21 of Bacillus phage SPP1 is a tail spike protein involved in binding to the receptor on the host and in DNA ejection.
