Just a little squeeze lets proteins assess DNA
Seven years ago, she figured out the structure of a protein called HincII that snips up DNA. The protein is a type of enzyme called a restriction endonuclease
and comes from Haemophilus influenzae bacteria.
Since that time, Horton has been trying to learn how HincII interrogates the DNA to find the ...

... therefore unaffected by the body's defences.
The research team found that the two enzymes essential to the bacteria's repair mechanism are AP endonuclease
and 3'-phosphodiesterase. Contrary to the scientists' expectations, these two enzymes carry out separate functions in the DNA repair process.
