phiGT1 gp10 family

Summary

The phiGT1 gp10 is a 52 residue frame found downstream of the major capsid protein gene. The purpose of the phiGT1 gp10 family build was to see if this small frame is widely distributed in related phages, and define the phylogenetic neighborhood around phiGT1 gp10 by a time tree for testing if it had descended coherently with the other phiGT1 structural genes.

Technical

Only a few homologs are found by Psi-Blast searching with phiGT1 gp10. Directed searching of prophages related to phiGT1 in the other structure module proteins revealed homologs also downstream of their major capsid protein genes. Some of these frames had not been predicted. Those sequences in the .a2m file identified by a nucleotide accession and a locus tag with an "a" appended are unannotated frames next to that locus tag in the bacterial genome indicated by the nucleotide accession.  Other technical details are as described.
