This modification enhances RNA stability and augments mRNA translation efficiency in eukaryotic cells, evidencing the enzyme's high tailing efficiency [1] [2].

Fmoc-L-Asn(EDA-N3)-OH is a chemical compound equipped with an azide group used in click chemistry. Reports in the literature have demonstrated its application in the modification of α-amanitin, the deadliest member of the amatoxin peptide family produced by the death cap mushroom. α-Amanitin is a highly lethal natural compound (LD50=50-100 µg/kg), an orally ingested rigid bicyclic octapeptide, acting as a highly selective conformational inhibitor of RNA polymerase II.

1-Methyladenosine-D3 hydrochloride is the deuterium-labeled hydrochloride salt form of 1-Methyladenosine. This compound is known as an RNA modification and serves as a tumor marker, as elevated levels in the body are associated with cancer development. Post-methylation, 1-Methyladenosine can drive liver tumor formation by upregulating PPARδ expression, regulating cholesterol metabolism, and activating the Hedgehog signaling pathway.

N4-Acetyl-2'-O-methylcytidine (ac4Cm) is a doubly modified RNA nucleoside bearing both N4-acetylation and 2'-O-methylation that is predominantly identified in thermophilic archaea.
