Welcome to the news page !

Here you will be informed of every change in PHROGs since its first release !
The annotations of PHROGs are flexible, any noticed problem or suggested change can be reported in the Suggestions page.

Annotation release v3 - July 7 2021

87 PHROG annotations were edited based on the expertized annotation of phages T4, T5,T7 and M13, while others were found to have no support for their past annotation and were thus modified.
You can check out these PHROGs on the table below, and download the latest annotation file at the end of this news thread.

Annotation release v2 - February 15 2021

A couple changes of annotation :
  • phrog_9896 is now annotated as phosphofructokinase
  • phrog_2185 is now annotated as RecT-like ssDNA annealing protein

  • These modifications are both based on PFAMs similar to these PHROGs.

       




    Annotation release v1

  • This is the initial annotation release.

  • You can download the annotation of all PHROGs as a tab separeted file file here :
