Abstract
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 b(6)f type, but exhibit some unexpected features as well. Evidence for high thermostability of the isolated protein and for its quinol substrate specificity is derived from EPR and kinetic measurements. A functional integration of this complex into an aerobic electron transfer scheme, connecting known dehydrogenase activities to the terminal oxidase branches of Thermus is outlined, as well as the specific principles of redox protein interactions prevailing at high temperature. Findings from this enzyme are linked to present knowledge on other menaquinol oxidizing bc complexes. (c) 2006 Elsevier B.V. All rights reserved.
