TL;DR: The purification of a stable dimeric ATP synthase supercomplex, using mitochondria of the alga Polytomella, is reported, revealing that dimer formation is based on specific interaction of the F0 parts, not the F1 headpieces which are not at all in close proximity.

TL;DR: Complex I of Arabidopsis includes five structurally related subunits representing γ-type carbonic anhydrases termed CA1, CA2, CA3, CAL1, and CAL2, which are proposed to contain a heterotrimer of three CA subunits anchored with their C termini to the hydrophobic arm of complex I.

TL;DR: A role of At1g47260 in mitochondrial one-carbon metabolism is supported by micro-array analyses and isolation of mitochondria and separation of mitochondrial protein complexes by Blue-native polyacrylamide gel electrophoresis or sucrose gradient ultracentrifugation revealed drastically reduced complex I levels.

TL;DR: The prime function of the supercomplex III2 + IV2 is proposed to be a scaffold for effective electron transport between complexes III and IV, and a pseudo-atomic model of their precise interaction is presented.

TL;DR: The discovery of additional supercomplexes in potato (Solanum tuberosum) mitochondria, which are of lower abundance and include cytochrome c oxidase (complex IV) and it is speculated that respirasomes are more abundant under in vivo conditions.
