Within the A4 phages, is it possible for the tail assembly chaperone gene not to have a frameshift and exist as two different genes, which is the way the genes have been annotated in LeoAvram and NorthStar. I am working on annotating phage LochMonster which is similar to these phages, but as all the other A4 have a frameshift, it seems wrong not to call a frameshift. I have compared the proteins and DNA and can't find a frameshift mutation. I wanted to double check before making the call that there is no frameshift.
Thanks,
Susan
