TO THE EDITOR Mitochondrial uncoupling, an increased permeability of the inner membrane to protons not coupled to ATP synthesis, dissipates mitochondrial membrane potential. Mild mitochondrial uncoupling is believed to prolong lifespan of certain model organisms by reducing the production of reactive oxygen species (ROS) and preventing oxidant damage (Brand, 2000). Indeed, long-lived Caenorhabd...
Two energy-dissipating systems, an alternative oxidase and an uncoupling protein, are known to exist in plant mitochondria. In tomato fruit mitochondria linoleic acid, a substrate for the uncoupling protein, inhibited the alternative oxidase-sustained respiration and decreased the ADP/O ratio to the same value regardless of the level of alternative oxidase activity. Experiments with varying con...
Antibodies against Escherichia coli-expressed uncoupling protein-2 (UCP2) and uncoupling protein-3 (UCP3) were raised by operating the blotted proteins into the spleen of minipigs. The antisera reacted more intensively with the recombinant UCP2 and UCP3 than with uncoupling protein-1 (UCP1) isolated from brown adipose tissue. Moreover, anti-UCP2 and cross-reacting anti-UCP3 antibodies identifie...
The reaction of two arginine-modifying reagents, phenylglyoxal and 2,3-butanedione, with a highly purified uncoupling protein of brown adipose tissue mitochondria decreased the GDP binding to the uncoupling protein. This inhibition was irreversible and dependent on time and concentration of the reagent. Complete inhibition of GDP binding by both reagents establishes that arginine is one of the ...
