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

Acanthamoeba castellanii causes infectious blindness and resides in a key evolutionary outgroup to humans and fungi. Its divergent mitochondria are of outstanding interest due to their predicted aerobic and anaerobic functions with potential for drug targeting. However, a detaile...

Acanthamoeba ATP synthase structure reveals the TCA cycle is tethered to OXPHOS

Oxidative phosphorylation (OXPHOS) is a key metabolic process that couples redox energy to ATP production. While some core OXPHOS complex subunits are found across all domains of life, many have diverged or expanded across evolution—as seen in the protozoan pathogen Acanthamoeba...
