Hydrophobic-cationic peptides modulate RNA polymerase ribozyme activity by accretion

Nature Communications, 2022
Macromolecular aggregates may have played an important role in the origin of life. Here, the authors report hydrophobic-cationic peptides that form insoluble aggregates, which reversibly accrete RNA on their surfaces, and enhance RNA polymerization by a ...
