Elucidating Evolutionary Mechanisms and Variants of the Hammerhead Ribozyme Using In Vitro Selection.

Abstract excerpt

The Hammerhead Ribozyme (HHR) is a ubiquitous RNA enzyme that catalyzes site-specific intramolecular cleavage. While mutations to its catalytic core have traditionally been viewed as detrimental to its activity, several discoveries of naturally occurring variants of the full-length ribozyme challenge this notion, suggesting a deeper understanding of HHR evolution and functionality. By systematically introducing...
