The mechanism of uncoupling of oxidative phosphorylation by 2,4-dinitrophenol.
2,4-Dinitrophenol fails to stimulate the breakdown of the soluble high energy intermediate of oxidative phosphorylation isolated from Alcaligenes faecalis extracts. Once the intermediate is broken down, by other reactions, the coupling enzyme is prevented from reassociation with the electron transport particles by 2,4-dinitrophenol. Phosphorylating particles washed with 2,4-dinitrophenol lose c...
متن کاملUncoupling proteins 2 and 3 alter mitochondrial membrane phospholipid fatty acyl composition in yeast
Mouse UCP1, human UCP2 and UCP3 were expressed in yeast (Saccharomyces cerevisiae). Total phospholipids were extracted and their fatty acyl composition was analysed. Expression of hUCP2 and hUCP3 significantly altered the mitochondrial phospholipid fatty acyl composition. Palmitoleoyl groups (16:1(n-7)) decreased while oleoyl groups (18:1(n-9)) increased, leading to a significant increase in th...
متن کاملJunctional Membrane Uncoupling
The permeability of the membrane surfaces where cells are in contact (junctional membranes) in Chironomus salivary glands depends on Ca(++) and Mg(++). When the concentration of these ions at the junctional membranes is raised sufficiently, these normally highly permeable membranes seal off; their permeability falls one to three orders, as they approach the nonjunctional membranes in conductanc...
متن کاملMembrane traffic: Cycling lipids
One of the more fascinating problems in biology is to understand the nerve signalling that enables us to think and feel. The transmission of nerve impulses across synapses is accomplished by the release of signalling molecules, known as neurotransmitters, at nerve terminals. Neurotransmitters are stored in synaptic vesicles and, after the nerve has received the appropriate stimulus, they are re...
متن کاملAdventures with membrane lipids.
It is a very great honour to have been awarded the Biochemical Society’s Morton Lectureship for 1994. T o be chosen by one’s peers for an award of this stature is indeed the ultimate reward for one’s life’s work, even more so when one considers the high level of achievement reached by Professor R.A. Morton himself and by the previous awardees. This award is particularly gratifying to me in reca...
