Structure-function relationships of the mitochondrial bc1 complex in temperature-sensitive mutants of the cytochrome b gene, impaired in the catalytic center N

Seven new structures of cytochrome b have been recently identified by isolating and sequencing revertants from cytochrome b respiratory deficient mutants (Coppee, J. Y., Brasseur, G., Brivet-Chevillotte, P., and Colson, A. M. (1994) J. Biol. Chem. 269, 4221-4226). These mutations are located in the...
