A recently resolved respiratory complex III, isolated from the extreme thermophile Thermus thermophilus, is discussed in terms of cofactor and subunit composition, and with respect to the origin of its protein modules. The four polypeptides, encoded by a single operon, share general homologies to canonical complexes both of the bc and b6f type, but exhibit(More)
Several components of the respiratory chain of the eubacterium Thermus thermophilus have previously been characterized to various extent, while no conclusive evidence for a cytochrome bc(1) complex has been obtained. Here, we show that four consecutive genes encoding cytochrome bc(1) subunits are organized in an operon-like structure termed fbcCXFB. The(More)
