Beschreibung
Zusammenfassung:	The present invention is related to the field of gene editing. In particular, the gene editing is directed toward single nucleotide base editing. For example, such single nucleotide base editing results in a conversion of a OG base pair to a T*A base pair. The high accuracy and precision of the presently disclosed single nucleotide base gene editor is accomplished by an NmeCas9 nuclease that is fused to a nucleotide deaminase protein. The compact nature of the NmeCas9 coupled with a larger number of compatible protospacer adjacent motifs provide the Cas9 fusion constructs contemplated herein to have a gene editing window that can edit sites that are not targetable by other conventional SpyCas9 base editor platforms.
