In this issue, Ikuro Abe et al. review modifications of prenyl side chains in natural product biosynthesis and Vincent Artero et al. summarize proton relays in molecular catalysis for hydrogen evolution and oxidation. The Minireviews deal with polymerization-induced chiral self-assembly of asymmetric suprastructures (Xiaoxiao Cheng, Wei Zhang), the combination of oxygen reduction and water oxidation for dual-pathway H₂O₂ production (Xiwang Zhang et al.), as well as hydrogenation reactions with heterobimetallic complexes (Preshit C. Abhyankar, Christine M. Thomas). In a Viewpoint Article, Matthias Beller et al. propose a protocol for unveiling the nature of photocatalytic hydrogen evolution reactions.

In the original research section, Beat Fierz et al. present a site-specific click chemistry approach to di-ubiquitinylate H1 variants that reveals a position-dependent stimulation of the DNA repair protein RNF168. Ellen M. Sletten et al. produced non-ionic fluorosurfactants for droplet-based in vivo applications. Luigi Petraccone et al. provide evidence of a stable RNA G-triplex structure at physiological temperatures in the SARS-CoV-2 genome (see picture). Eva Zurek et al. explain why Mg₂IrH₆ is predicted to be a high-temperature superconductor, but Ca₂IrH₆ is not.
