A3G binding to RNA

Patent Pending APOBEC3G (apolipoprotein B mRNA-editing, enzyme-catalytic, polypeptide-like 3G) is a human enzyme encoded by the APOBEC3G gene that belongs to the APOBEC superfamily of proteins.[1] This family of proteins has been suggested to play an important role in innate anti-viral immunity.[2] APOBEC3G belongs to the family of cytidine deaminases that catalyze the deamination of cytidine to uridine in the single stranded DNA substrate.[1] The C-terminal domain of A3G renders catalytic activity, several NMR and crystal structures explain the substrate specificity and catalytic activity
