General annotation (Comments)

Function

Non-covalently bound to the neck of the phage capsid and essential for phage adsorption to the bacterial host. It displays endorhamnosidase enzymatic activity, hydrolyzing the alpha-1,3-O-glycosidic linkage between rhamnose and galactose of the O-antigen polysaccharide.

Subunit structure

Homotrimer.

Domain

The interdigitation of the polypeptide chains at the C-termini is important to protrimer formation in the folding pathway and to thermostability of the mature protein.

Sequence similarities

To phage SF6 tsp and to phage APSE-1 p36.
