Abstract
|
|
|
SPP1 is a siphophage infecting the gram-positive bacterium Bacillus subtilis. It
is constituted by an icosahedric head and a long non-contractile tail formed by
gene products (gp) 17-21. A group of 5 small genes (gp 22-24.1) follows in the
genome those coding for the main tail components. However, the belonging of the
corresponding gp to the tail or to other parts of the phage is not documented.
Among these, gp22 lacks sequence identity to any known protein. We report here
the gp22 structure solved by X-ray crystallography at 2.35 A resolution. We
found that gp22 is a monomer in solution and possesses a significant structural
similarity with lactococcal phage p2 ORF 18 N-terminal "shoulder" domain.
