tail fiber protein [Klebsiella phage Matisse]
pyocin knob domain-containing S74 family peptidase( domain architecture ID 15331435)
pyocin knob domain-containing S74 family peptidase with an N-terminal domain similar to R-type pyocins, which are high-molecular weight bacteriocins produced by some strains of Pseudomonas aeruginosa to specifically kill other strains of the same species, and a C-terminal S74 family serine endopeptidase similar to the chaperone domain of Escherichia coli phage K1F endosialidase

Chaperone of endosialidase; 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, pfam12219. The endosialidase protein forms homotrimeric molecules in bacteriophages. 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. : Pssm-ID: 404724 Cd Length: 56 Bit Score: 67.27 E-value: 7.83e-14

knob domain of R1 and R2 pyocins and similar domains; The knob domain is present as a tandemly repeated structural domain in R-type pyocins, which are high-molecular weight bacteriocins produced by some strains of Pseudomonas aeruginosa to specifically kill other strains of the same species. R-type pyocins are structurally similar to simple contractile tails, such as those of phage P2 and Mu, and they punch a hole in the bacterial envelope to efficiently kill target cells. The second knob domain may contain regions responsible for determining the killing spectrum. Knob-like domains occur in host-recognition and binding proteins of, not only pyocins, but also phages, such as in phage K1F endosialidase (not represented by this model), where it may interact with sialic acid, the cell surface molecule that is recognized during infection. : Pssm-ID: 410997 [Multi-domain] Cd Length: 80 Bit Score: 44.63 E-value: 1.40e-05
