Tóm tắt

Alternative complex III (ACIII) is an enzyme of electron transport chains in some bacterial species. ACIII, like cytochrome bc enzymes, oxidizes quinol and transfers electrons from quinol to electron acceptors located outside the membrane. Various proteins can functionally link ACIII with other enzymes. The structure of ACIII from Flavobacterium johnsoniae suggests that in this bacterium the membrane-anchored mobile mono-heme cytochrome c domain (mdA) of the ActA subunit of ACIII provides means for its connection with cytochrome aa
