Metabolism of carbon tetrachloride to phosgene

Life Sciences, 1980
Abstract Aerobic incubation of hepatic microsomal fractions in the presence of carbon tetrachloride, NADPH and cysteine resulted in the formation of phosgene which was identified by gas chromatography/mass spectrometry as the adduct, 2-oxothiazolidine-4-carboxylic acid, formed by its reaction with cysteine.

Metabolic modulation of transcription: The role of one-carbon metabolism

Cell Chemical Biology, 2022
While it is well known that expression levels of metabolic enzymes regulate the metabolic state of the cell, there is mounting evidence that the converse is also true, that metabolite levels themselves can modulate gene expression via epigenetic modifications and transcriptional regulation.

Regulation of Carbon Metabolism in Bacteria

1997
Bacteria have different regulatory systems to control carbon metabolism, in a number of cases employ the phosphoenolpyruvate phosphotransferase system (PTS) is used, to tune the transport of carbohydrate and/or transcription of genes specifying catabolic enzymes.

Carbon and nitrogen metabolism in Rhizobium

2000
One of the paradigms of symbiotic nitrogen fixation has been that bacteroids reduce N2 to ammonium and secrete it without assimilation into amino acids. This has recently been challenged by work with soybeans showing that only alanine is excreted in 15N2 labelling experiments.

Introduction to Carbon Metabolism in Yeast

2014
Yeast fermentation of different plant carbohydrate sources, like grape must, is one of the oldest human technologies and its origins date back to the Neolithic period. These fermentations were initially spontaneous and their chemical, physiological, or microbiological background were not understood until the late eighteenth century.

The Two-Carbon Chain in Metabolism

JAMA: The Journal of the American Medical Association, 1963
THE IMPACT of the nutritional environment upon an organism cannot be appreciated without reference to cellular physiology and to the biochemical events which underlie cell function. The science of biochemistry, therefore, has become increasingly important in the interpretation of nutritional effects and, for that matter, of all the properties and ...

Photosynthesis. Carbon Metabolism: The Carbon Metabolisms of Unstressed and Stressed Plants

1997
Following on from the pioneer experiments of investigators such as Joseph Priestly and Jan Ingenhousz, Nicolas de Saussure must have felt close to a full explanation of the growth of plants when he concluded that plant dry matter originated predominantly from water and air.

Modes of cyanobacterial carbon metabolism

Annales de l'Institut Pasteur / Microbiologie, 1983
Resume Dans leur environnement naturel, les cyanobacteries ont a faire face, non seulement aux fluctuations d'aliments nutritifs mais aussi a l'alternance journaliere de lumiere et d'obscurite. Leur capacite d'adaptation a de telles variations implique un degre de flexibilite metabolique considerable.

Schizophrenia and single-carbon metabolism

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2005
Schizophrenic patients generally appear to have a disturbed single-carbon metabolism. Methionine and homocysteine are intermediary metabolites in this metabolic system. In a case-control study of the cerebrospinal fluid, a majority of the patients had elevated methionine and a smaller subgroup had elevated homocysteine.

The effects of carbon-14 exposure on photosynthetic energy metabolism and carbon metabolism in microalgae

Journal of Environmental Radioactivity
Carbon-14 (14C) is one of the main radioactive elements in nuclear power plant effluent, but research on its ecological risk remains limited. This study aims to analyze the responses of photosynthetic performance and metabolic profiling in microalgae under 14C exposure and explore the effect of 14C on microalgae.
