Ribozyme methylation
Webb1 apr. 2003 · Ribozymes are RNA molecules with catalytic activity. Since their discovery in the early eighties [1], RNA chemical catalysis has been described in several essential biological processes such as RNA splicing, RNA processing, the replication of RNA genomes, and peptide bond formation during translation [ 2–5 ]. WebbMany viruses have evolved mechanisms for generating their own cap structures with methylation at the N7 position of the capped guanine and the ribose 2'-Oposition of the …
