Sorry, we have not found any functional associations in our database.
Your input was '511145.b1561' (Qin prophage).
Unfortunately, this gene is not a member of an orthologous group, which is a prerequisite for STRING when working in 'COG'-mode.
You may re-try in 'protein'-mode: Go back to the input-page and switch the requested interactors to 'proteins'.
Please note that, in COG-mode, STRING works best for prokaryotes - although it does contain orthologous groups for eukaryotes as well (KOG groups).
In general, orthology information is derived from the COG database, which we extended to cover more species and more genes, using an automatic update mechanism.
