Sequence specificity of DNA cleavage by Micrococcus luteus gamma endonuclease.


DNA fragments of defined sequence have been used to determine the sites of cleavage by gamma-endonuclease activity in extracts prepared from Micrococcus luteus. End-labeled DNA restriction fragments of pBR322 DNA that had been irradiated under nitrogen in the presence of potassium iodide or t-butanol were treated with M. luteus gamma endonuclease and… (More)
