Properties of dna and rna ligases

WebMar 5, 2024 · Ligases catalyze the formation of a phosphodiester bond between juxtaposed 5' phosphate and 3' hydroxyl termini of nucleotides (potentially RNA or DNA depending on the ligase). In a sense, they are the opposite of restriction endonucleases, but they do not appear to be influenced by the local sequence, per se.

DNA Damage Recognition and Repair by DNA Ligases

WebViruses are divided into DNA viruses and RNA viruses. DNA viruses are recognized by TLRs (toll-like receptors) and cGAS(cyclic GMP-AMP synthetase). RNA viruses, on the other hand, are recognized by RLRs (RIG-I like receptors), such as RIG-I, MDA5, and LGP2. Both TLRs and RLRs belong to pattern recognition receptors (PRRs).
