Reactions of cytochrome oxidase.
In 1939 Keilin and Hartree (2) advanced the concept that there are two cytochrome components reacting between cytochrome c and oxygen; namely, cytochrome a and cytochrome a3. They based their hypothesis principally on the action of carbon monoxide which caused the a-band of reduced cytochrome a to spread toward 590 rnp and the r-band at 448 rnp to shift to 430 rnp and to be replaced by a very p...
متن کاملCytochrome oxidase of cactus.
The present autlhors have isolated a particleassociated cytochrome oxidase from the phylloclades of cactus plant and studied its kinetics. To our knowledge, this is the first report on cytoclhrome oxidase from a crassulacean plant. Tender phylloclades of Nopalea dejecta SalmDyck were ground with 5 volumes of chilled medium in a Waring Blendor operated first at low speed for 25 seconds and then ...
متن کاملStudies on cytochrome oxidase. IV. The cytochrome oxidase activity.
where the activity is determined by measuring the rate of oxidation of reduced cytochrome c. Smith (6, 7), Conrad (8, 9), Wainio (10-13) et ~2. have extensively investigated the effect of various factors on the cytochrome oxidase activity measured by System 2 with soluble and insoluble preparations of cytochrome oxidase, whereas among those (14-30) who have employed System 1, Slater (5), using ...
متن کاملTwo-dimensional crystallization of monomeric bovine cytochrome c oxidase with bound cytochrome c in reconstituted lipid membranes
Mitochondrial cytochrome c oxidase utilizes electrons provided by cytochrome c for the active vectorial transport of protons across the inner mitochondrial membrane through the reduction of molecular oxygen to water. Direct structural evidence on the transient cytochrome c oxidase-cytochrome c complex thus far, however, remains elusive and its physiological relevant oligomeric form is unclear. ...
متن کاملCrystallization of cytochrome bc1 complex.
Complex III (cytochrome bc1 particle; ubiquinol:ferricytochrome c oxidoreductase, EC 1.10.2.2) was purified from beef heart mitochondria by a combination of hydrophobic interaction and affinity chromatography. By washing the complex with detergent on the hydrophobic interaction column, phospholipids were effectively depleted; 7 mol of cardiolipin per mol of cytochrome c1 was retained in the fin...
