    Abstract: Proposed are an adenine base editor having increased thymine-cytosine sequence-specific cytosine base editing activity, a cytosine base editing method, and a cytosine base editing kit. The editor, produced by introducing a P48R mutation into an adenosine deaminase, has an operating range that is more sophisticated than conventional cytosine base editors, allows cytosine base editing only when cytosine is positioned right behind thymine, thereby enabling elaborate editing even when there is a plurality of cytosines within the range, and enables cytosine to be substituted with thymine or guanine in the presence or absence of UGI, respectively. Therefore, the cytosine base editing composition can be effectively used in the fields of gene therapy or new crop development which requires precise editing of only cytosine in all living organisms, including humans, plants, and bacteria.
