The incorporation of formate-C14, glycine-2-C14, adenine-4, 6-C14, and phosphate-P32 into nucleic acids.
nine labeled either with C'4 or N'5. Considerable controversy has developed as to which one of these tracer compounds gives an accurate measurement of the “relativeturnover-rate― of the nucleic acids. In order to determine the “absolute turnover rate― of the nucleic acids, it is necessary to know the specific activity of the immediate precursor of the nucleic acids. Since even the ident...
متن کاملThe incorporation of glycine-1-C14 by typhus rickettsiae.
A previous study has shown that under suitable conditions typhus rickettsiae can incorporate small but significant quantities of labeled methionine. For maximal uptake, adenosine 5’-triphosphate, glutamine, all of the naturally occurring amino acids, the mononucleotides, diphosphopyridine nucleotide, glutathione, and a soluble protein fraction from normal yolk sac tissues were required (1). In ...
متن کاملPhotosynthesis by isolated chloroplasts.
Photosynthesis in green plants requires not only photoelectron transport, oxygen evolution, and photophosphorylation, but also the synthetic reactions whereby carbon dioxide is assimilated and reduced to a number of organic compounds via the photosynthetic carbon reduction cycle1 and secondary biosynthetic pathways.2 Complete photosynthesis with isolated chloroplasts has for many years been a g...
متن کاملThe influence of vitamin E deficiency on the metabolism of sodium formate-C14 and glycine-1-C14 by the rabbit.
Several recent, reports from this laboratory have implicated vitamin E in the metabolism of the nucleic acids. It was shown that vitamin E-deficient rabbits excrete extra quantities of allantoin (1) and that the livers from such animals exhibit greatly increased xanthine oxidase activities (2). Finally it haa been shown that vitamin E deprivation in the rat, leads to an increased incorporation ...
متن کاملEffect of estradiol on the metabolism of serine-3-C14 in surviving uterine segments.
Previous studies on the metabolism of formate and glycine in surviving uterine segments from estrogen-treated rats have revealed the high sensitivity of certain “l-carbon” metabolic pathways as indicators of early estrogenic action (1, 2). In the present paper these studies have been extended with serine-3-C14. In response to 6 hours pretreatment with estradiol, the incorporation of radioactivi...
