The paper studies the evolution of nonribosomal peptides in entomopathogenic bacteria, finding evidence of both neutral drift and natural selection driving structural convergence and toxicity diversification.

The paper determines the in situ structure of a high-torque bacterial flagellar motor using cryogenic electron microscopy, revealing protein adaptations and universal principles of torque generation.

The paper infers a general substitution matrix for structural phylogenetics and uses it to provide evidence for a root between archaea and bacteria.
