Rna editing deamination

WebMar 9, 2024 · Human APOBEC3A (A3A) is a nucleic acid-modifying enzyme that belongs to the cytidine deaminase family. Canonically, A3A catalyzes the deamination of cytosine into uracil in single-stranded DNA, an activity that makes A3A both a critical antiviral defense factor and a useful tool for targeted genome editing. However, mutagenesis by A3A has … WebApr 7, 2024 · DOI: 10.1016/j.coviro.2024.101326 Corpus ID: 258028741; The roles of nucleic acid editing in adaptation of zoonotic viruses to humans @article{Ratcliff2024TheRO, title={The roles of nucleic acid editing in adaptation of zoonotic viruses to humans}, author={Jeremy D Ratcliff and Peter Simmonds}, journal={Current Opinion in Virology}, …
