One-carbon metabolism and epigenetics

Molecular Aspects of Medicine, 2017
The function of one-carbon metabolism is that of regulating the provision of methyl groups for biological methylation reactions including that of DNA and histone proteins. Methylation at specific sites into the DNA sequence and at histone tails are among the major epigenetic feature of mammalian genome for the regulation of gene expression. The enzymes

Heterotrophic Carbon Metabolism

2005
Publisher Summary The chapter focuses on the heterotrophic processes of carbon mineralization. The relationship between microbial activity and carbon source are considered and the role of microorganisms in the detritus food chain is studied. The chapter outlines the various pathways of both aerobic and anaerobic organic carbon mineralization.

Unfamiliar metabolic links in the central carbon metabolism

Journal of Biotechnology, 2014
The central carbon metabolism of all organisms is considered to follow a well established fixed scheme. However, recent studies of autotrophic carbon fixation in prokaryotes revealed unfamiliar metabolic links. A new route interconnects acetyl-coenzyme A (CoA) via 3-hydroxypropionate with succinyl-CoA.

CARBON AND CARBONATE METABOLISM IN COASTAL AQUATIC ECOSYSTEMS

Annual Review of Ecology and Systematics, 1998
▪ Abstract  The coastal zone is where land, ocean, and atmosphere interact. It exhibits a wide diversity of geomorphological types and ecosystems, each one displaying great variability in terms of physical and biogeochemical forcings. Despite its relatively modest surface area, the coastal zone plays a considerable role in the biogeochemical cycles ...

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.
