A GTP synthase ribozyme with increased GTP turnover.

Abstract excerpt

Before the invention of encoded protein translation, early stages of life likely relied on catalytic RNAs (ribozymes). To test how such a system could have functioned, researchers have developed ribozymes that could have provided central functions. The central function of self-replication would have required templated RNA polymerization of nucleotides, which is energetically driven in today's life forms by the...
