Ammonia formation in isolated rat liver mitochondria.
Studies of isolated rat liver mitochondria were undertaken in order to evaluate the importance of glutamate transport, oxidation reduction state, and product inhibition on the rates of formation of ammonia from glutamate. Uptake and efflux of glutamate across the mitochondrial membrane were measured isotopically in the presence of rotenone. Efflux was stimulated by H+ in the mitochondrial matri...

متن کاملUptake of protoporphyrin IX by isolated rat liver mitochondria.
Rat liver mitochondria accumulate protoporphyrin IX from the suspending medium into the inner membrane in parallel with the magnitude of the transmembrane K+ gradient (K+in/K+out). Only protoporphyrin IX taken up in parallel with the transmembrane K+ gradient is available for haem synthesis. Coproporphyrins (isomers I and III) are not taken up by the mitochondria. The results support the sugges...
متن کاملThymidine incorporation into deoxyribonucleic acid by isolated rat liver mitochondria.
Isolated rat liver mitochondria can incorporate tritiated thymidine into DNA. The addition of deoxyribonucleotides and ATP are necessary. The process of incorporation was found to be inhibited to the extent of 92% by actinomycin D and only 14% by pancreatic deoxyribonuclease. The identification of the labeled product as mitochondrial DNA is supported by its insolubility in acid, resistance to a...
متن کاملBiosynthesis of cytochrome c oxidase by isolated rat liver mitochondria.
When isolated mitochondria which have been labeled with [3H]leucine are solubilized and treated with anti-serum specific for cytochrome c oxidase, labeled polypeptides which correspond to the three largest polypeptides of this enzyme are immunoprecipitated. This indicates that the three largest polypeptides of cytochrome c oxidase which have Mr of 66,000, 39,000, and 23,000 are synthesized by i...
