WebDec 8, 2024 · The circularly permuted construct (CapD-CP) shifts the nucleophilic Thr 352 residue to the N terminus and removes the requirement of internal autoproteolysis, which improves the production of homogeneous protein. In addition, the CapD-CP has greater thermostability than native CapD (CapD-N) ( 29 ). WebRNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre-mRNA) transcript is transformed into a mature messenger RNA ().It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions).
