Abstract

The present disclosure provides new RNA-guided nucleases for making rational, direct edits to nucleic acids in live cells.

First claim

We claim:

1. A nuclease system capable of performing nucleic acid-guided nuclease editing, wherein the nuclease system is selected from a nuclease system comprising SEQ ID NO: 1, SEQ ID NO: 20 and SEQ ID NO: 21; a nuclease system comprising SEQ ID NO: 1, SEQ ID NO: 22 and SEQ ID NO: 23; and a nuclease system comprising SEQ ID NO: 1, SEQ ID NO: 24 and SEQ ID NO: 25.

2. The nuclease system of claim 1 comprising SEQ ID NO: 1, SEQ ID NO: 20 and SEQ ID NO: 21.

3. The nuclease system of claim 1 comprising SEQ ID NO: 1, SEQ ID NO: 22 and SEQ ID NO: 23.

4. The nuclease system of claim 1 comprising SEQ ID NO: 1, SEQ ID NO: 24 and SEQ ID NO: 25.

5. A nickase having an amino acid sequence selected from SEQ ID NOs: 14 and 15.

6. A dead nuclease having the amino acid sequence of SEQ ID NO: 16.
