Genetic data revealed existing drugs that could be repurposed to improve lung function, with evidence that compounds which control blood glucose could be particularly useful for respiratory impairment.

The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.

A conserved element in the flavivirus genomic 5′ terminus switches its conformation in response to long-range RNA interactions, and thereby regulates the dynamic recruitment of viral replicase for efficient viral RNA replication.

A combination of X-ray crystallography, molecular dynamics and small angle X-ray scattering shows that the transcription antiterminator M2-1 is a structurally dynamic homotetramer that undergoes large concerted conformational changes upon binding its target RNA.
