Merged summary
TL;DR - The bacteriophage kinase T7K phosphorylates nearly all bacterial proteins, with a preference for DNA-binding proteins. This broad activity helps the virus disable host defence systems that target nucleic acids.
- T7K acts as an unusually indiscriminate kinase across the bacterial proteome.
- Its bias toward DNA-binding proteins gives the enzyme functional specificity despite its broad activity.
- Phosphorylating these proteins enables the virus to counter bacterial nucleic-acid defence mechanisms.
- The finding reveals a viral strategy that uses widespread host-protein modification to overcome immunity.
