an engineered guide nucleic acid capable of complexing with the nucleic acid-guided nuclease; and
an editing sequence encoding a nucleic acid complementary to the target region having a change in sequence relative to the target region and a mutation in a protospacer adjacent motif (PAM) sequence; and
(b) allowing the nuclease, guide nucleic acid and editing sequence to create a genome edit in a target region of the genome of the cell.

3 . The method of claim 1 , wherein the engineered guide nucleic acid comprises SEQ ID No. 88, SEQ ID No. 93 or SEQ ID No. 94.
4 . The method of claim 1 , wherein the nucleic acid-guided has less than 40% protein identity to SEQ ID No. 12 and SEQ ID No. 108.
5 . The method of claim 1 , wherein the nucleic acid-guided nuclease is codon optimized for the cell to be edited.
6 . The method of claim 5 , wherein the nucleic acid-guided nuclease is codon optimized for E. coli.
7 . The method of claim 5 , wherein the nucleic acid-guided nuclease is codon optimized for S. cerevisiae.
8 . The method of claim 5 , wherein the nucleic acid-guided nuclease is codon optimized for mammalian cells.
9 . The method of claim 1 , wherein the non-naturally occurring nucleic acid-guided nuclease is encoded by a nucleic acid having at least 95% identity to SEQ ID No. 22, SEQ ID No. 42, SEQ ID No. 128 or SEQ ID No. 148.
10 . The method of claim 1 , wherein the non-naturally occurring nucleic acid-guided nuclease is encoded by a nucleic acid having greater than 95% identity to SEQ ID No. 22, SEQ ID No. 42, SEQ ID No. 128 or SEQ ID No. 148.
11 . A nucleic acid-guided nuclease system comprising:
(a) a non-naturally occurring nuclease encoded by a nucleic acid having at least 90% identity to SEQ ID No. 22, SEQ ID No. 42, SEQ ID No. 128 or SEQ ID No. 148;
(b) an engineered guide nucleic acid capable of complexing with the nucleic acid-guided nuclease, and
(c) an editing sequence having a change in sequence relative to the sequence of a target region in a genome of a cell and a mutation in a protospacer adjacent motif (PAM) sequence; wherein the system results in a genome edit in the target region of the genome of the cells facilitated by the nuclease, the engineered guide nucleic acid and the editing sequence.
