Growth, Dissolution and Segregation of Genetically Encoded RNA Droplets by Ribozyme Catalysis
Angewandte Chemie, EarlyView.Ribozymes enable sequence‐encoded turnover of RNA droplet material, resulting in transiently active droplets that selectively segregate based on their genotype. This establishes a direct link between genetic information and droplet behavior, marking a step toward programmable, evolvable RNA‐based compartments with life‐like properties.

Multiple prebiotic metals mediate translation. [PDF]
, 2018 Today, Mg2+ is an essential cofactor with diverse structural and functional roles in life's oldest macromolecular machine, the translation system. We tested whether ancient Earth conditions (low O2, high Fe2+, and high Mn2+) can revert the ribosome to a ...

A Faster Triphosphorylation Ribozyme. [PDF]
, 2015 In support of the RNA world hypothesis, previous studies identified trimetaphosphate (Tmp) as a plausible energy source for RNA world organisms. In one of these studies, catalytic RNAs (ribozymes) that catalyze the triphosphorylation of RNA 5'-hydroxyl ...

Horizontal transfer between loose compartments stabilizes replication of fragmented ribozymes
, 2019 The emergence of replicases that can replicate themselves is a central issue in the origin of life. Recent experiments suggest that such replicases can be realized if an RNA polymerase ribozyme is divided into fragments short enough to be replicable by ...
