Evolution of a General RNA-Cleaving FANA Enzyme
Abstract
Artificial genetic polymers (XNAs) have been explored for their nuclease activity, but XNAzymes have proven challenging to discover by in vitro selection. Here, the authors generate an efficient RNA-cleaving 2’-fluoroarabino nucleic acid enzyme (FANAzyme) by in vitro evolution using natural DNA polymerases.
