WebJul 2, 2024 · The cleavage site of the hatchet ribozyme is located at the 5′ end of stem P1—a distal location like that in the HDV-like ribozyme. Modeling of C(−1) into the active site pocket suggested that N7 of G31 may act as the general base to deprotonate the 2′-OH of C(−1) for nucleophilic attack. 59 A hatchet variant with 7-deazaguanosine in ... WebBackground: The hatchet ribozyme is an RNA structure that catalyzes its own cleavage at a specific site. In other words, it is a self-cleaving ribozyme. Hatchet ribozymes were discovered by a bioinformatics strategy [1] as RNAs Associated with Genes Associated with Twister and Hammerhead ribozymes, or RAGATH.
