T4 DNA Ligase
WebSep 12, 2002 · T4 RNA ligase ( 1) is the founding member of a family of RNA end-joining enzymes involved in RNA repair, splicing, and editing pathways ( 2 – 8 ). T4 RNA ligase joins 3′ OH and 5′ PO 4 RNA termini by means of three nucleotidyl transfer steps similar to those of DNA ligases ( 9 – 11 ). WebMay 21, 2024 · Previously, RNA circularization was achieved by T4 RNA ligase 2 (Rnl2, a dsRNA ligase) using splints, but the yield was low due to concurrent intermolecular polymerization. Here, various functional RNAs (siRNA, miRNA, ribozyme, etc.) are dominantly converted by Rnl2 to the rings without significant limitations in sizes and … is iphone se 4g
