Mitochondrial proteome of Acanthamoeba delineates aerobic and anaerobic pathways dynamically regulated by oxygen

SUMMARY Acanthamoeba castellanii causes infectious blindness and is a key evolutionary outgroup to humans and fungi. Its divergent mitochondria are of outstanding interest due to predicted aerobic and anaerobic functions with potential for drug targeting. However, a detailed delineation of its bioenergetic machinery, t...

Conserved and divergent mitochondrial assemblies in kinetoplastid parasites

SUMMARY The mitochondrial proteomes of Leishmania tarentolae and Trypanosoma brucei contain ~1,700 proteins, most of which lack homologs in higher eukaryotes. Here, we integrate complexome profiling and cryo-electron microscopy to define conserved and lineage-specific macromolecular assemblies that support mitochondria...

Seed-Guided De Novo Design Expands the Structural Diversity of Antitoxin Protein Binders

These results establish motif scaffolding of surface-complementing seeds as an effective strategy for overcoming current limitations of de novo generative models, enabling the design of proteins that can engage challenging interface sites.
