NOVEL ENDORIBONUCLEASE

摘要

A novel endoribonuclease activity exhibiting polypeptide; a nucleic acid coding for the polypeptide; a recombinant DNA comprising the nucleic acid; a transformant obtained by transformation using the recombinant DNA; a process for producing the polypeptide, characterized by including the steps of culturing the transformant and collecting the polypeptide from the culture; a process for producing single-strand RNA fragments, characterized by including the step of causing the polypeptide to act on a single-strand RNA; and a method of fragmenting a single-strand RNA.
