IISc discovers protein protecting tuberculosis bacteria
Scientists in India found a special protein called Lsr2 in the bacteria that causes tuberculosis.
This protein helps the bacteria by stopping foreign DNA from changing its own DNA.
Foreign DNA can come from viruses or other processes.
The researchers think this happens over millions of years.
This discovery helps us understand how the tuberculosis bacteria protect themselves and might help in finding new ways to treat tuberculosis.
IISc researchers discovered a protein called Lsr2 in tuberculosis bacteria.
Lsr2 silences foreign DNA in the bacteria, protecting it from changes.
Foreign DNA can come from viruses or other processes like transduction.
The process happens over millions of years on an evolutionary scale.
This discovery helps understand how tuberculosis bacteria protect themselves.
