Candidates for tail side fiber assemblies in the φRIO-1 structure homology group of phages. Open segments have no discernible sequence similarity to any other sequence. Most of the other labeled domains are easily recognizable by PSI-BLAST, with the following two exceptions. The red domain clearly matches between φRIO-1 and SIO1, but recognition of it throughout the homology group required the progressive HMM building procedure described in methods. The blue block indicating a similarity between φRIO-1 gp55 and CW02 gp54 when formed to a two sequence profile only weakly matches to the Pfam: phage_fiber_2 family. Pfam: PF12789 is a Pfam protein domain family. CD: PHA00439 refers to an NCBI protein family. SIO1 gp5.2 refers to an unannotated gene between annotated genes for gp5.1 and gp6.
