Nucleobase deamination can be used to map N6-methyladenosine in RNA, but existing deamination methods are harsh, limiting applications. Now a method for the N-nitrosation of RNA based on organocatalyst and Lewis acid co-catalysis has been shown to enable sensitive N6-methyladenosine mapping with minimal background noise and high detection efficiency.
