CRYSTAL STRUCTURE OF THE HEAD-BINDING DOMAIN OF PHAGE P22 TAILSPIKE PROTEINCRYSTAL STRUCTURE OF THE HEAD-BINDING DOMAIN OF PHAGE P22 TAILSPIKE PROTEIN
Structural highlights
1lkt is a 6 chain structure with sequence from Salmonella virus P22. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
FIBER_BPP22 Structural component of the short non-contractile tail. The tail comprises six fibers that mediate primary attachment to the host cell lipopolysaccharides (LPS) and display endorhamnosidase enzymatic activity, hydrolyzing the alpha-1,3-O-glycosidic linkage between rhamnose and galactose of the O-antigen polysaccharide. Digestion of the LPS brings the capsid near the cell outer membrane.[1][2]
