    ..These differences between the structures could reflect conformational changes that take place upon deprotonation of E(I-286) during turnover of the wild-type enzyme, which could be part of the proton-pumping machinery of the enzyme...

    ..The activated state was characterized by a higher number of correlated transitions as well as a higher number of amino acids associated with electron transfer...

    ..Our results indicate that the mutation lowers activity indirectly by slowing the uptake of protons through the D-channel and that the three histidine residues stabilize the interactions between subunit I and subunit III. ..

    ..In conclusion, these results show that the phospholipids regulate events occurring during electron transfer activity by maintaining the structural integrity of the enzyme at the active site. ..
