FIG. 4.

Comparison of the presumed tail fiber proteins of the K139-related phages. Similar shading of boxes within the proteins indicates sequence similarity of ≥80%; different shading indicates similarity of ≤42%. The two regions with homology to tail fiber proteins of other phages are indicated by different patterns. The asterisk marks the fragment sequence of V. cholerae classical strain Z17561, which was derived from the database. V1 and V2, variable regions 1 and 2; C1 and C2, conserved regions 1 and 2; aa, amino acids.
