    It was previously reported that disruption or deletion of QCR6, the nuclear gene encoding subunit 6 of the cytochrome bc1 complex, does not impair growth of yeast on non-fermentable carbon sources (Schoppink, P. J., Hemrika, W., Reyne, J...

    ..We suggest that Shy1 links Cox1 translational regulation to complex IV assembly and supercomplex formation. ..

    ..Based on our findings, we propose a model where the Hig1 proteins regulate the COX enzyme activity through Cox3 and associated Cox12 protein, in a manner that may be influenced by the neighboring AAC proteins. ..

    ..We propose that Bcs1p acts as an ATP-dependent chaperone, maintaining the precomplex in a competent state for the subsequent assembly of the Rieske FeS and Qcr10p proteins. ..

    ..Likewise, evidence of interactions between subunit 6, subunit 9 and cytochrome c1 suggests that a subcomplex between these two supernumerary subunits and the cytochrome might exist. ..
