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 right...
