Fig. (1) Domain organization of Gp07. (A) Pfam analysis indicates that Gp07 harbours two domains- the amino terminal Bro domain and carboxy terminal KilA domain; the first eleven unique amino acids are coloured gray. (B) Phylogenetic analysis of Phi11 Gp07 has been aligned with ClustalO (See Materials and Methods for details) by neighbour-joining method. The Phi11 is evolutionary closely related with phage 42E.
