Fig. (2) Sequence analysis of the full-length protein of some phages in Caudovirales. Sequences are designated by their phage name and followed by protein length. Phi11 Gp07 has been aligned with ClustalO (See Materials and Methods for details). The coloring reflects the conservation profile at clustal consensus of amino acids. ‘*’ identical residues (M,F,A,L,G,E,Y), all shaded green. ‘ : ’ highly conserved residues (Q,V,I,E,N,D,Y,F) shaded yellow. ‘ . ’ weakly conserved residues (S,D,E,F,V,R,Q,N,K) shaded turquoise. Phage Phi11 unique residues region (MWVLRKKEDTQ) all coloured gray.
