Abstract excerpt

The mouse LA9 HQN-R11 cytochrome b mutant, in which the glycine residue at position 231 is replaced by aspartic acid, has increased resistance to all inhibitors of the Qn redox center. It is shown here that this single amino acid alteration has multiple and unexpectedly diverse effects upon the m...
