ABSTRACT
|
|
|
| |
|
All 13 lipids, including two cardiolipins, one phosphatidylcholine, three
phosphatidylethanolamines, four phosphatidylglycerols and three triglycerides,
were identified in a crystalline bovine heart cytochrome c oxidase (CcO)
preparation. The chain lengths and unsaturated bond positions of the fatty acid
moieties determined by mass spectrometry suggest that each lipid head group
identifies its specific binding site within CcOs. The X-ray structure
demonstrates that the flexibility of the fatty acid tails facilitates their
effective space-filling functions and that the four phospholipids stabilize the
CcO dimer. Binding of dicyclohexylcarbodiimide to the O(2) transfer pathway of
CcO causes two palmitate tails of phosphatidylglycerols to block the pathway,
suggesting that the palmitates control the O(2) transfer process.The
phosphatidylglycerol with vaccenate (cis-Delta(11)-octadecenoate) was found in
CcOs of bovine and Paracoccus denitrificans, the ancestor of mitochondrion,
indicating that the vaccenate is conserved in bovine CcO in spite of the
abundance of oleate (cis-Delta(9)-octadecenoate). The X-ray structure indicates
that the protein moiety selects cis-vaccenate near the O(2) transfer pathway
against trans-vaccenate. These results suggest that vaccenate plays a critical
role in the O(2) transfer mechanism.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
codes are
shown on the right.
