The presence of acetyl groups of histones
The introduction of an acetyl group into a molecule is called acetylation. In biological organisms, acetyl groups are commonly transferred from acetyl-CoA to other organic molecules. Acetyl-CoA is an intermediate both in the biological synthetase and in the breakdown of many organic molecules. Acetyl-CoA is also created during the second stage of cellular respiration, pyruvate decarboxylation, by the action of pyruvate dehydrogenase on pyruvic acid. WebbHistone deacetylases (HDAC) are a class of enzymes that remove acetyl groups from an amino acid on a histone. This is important because DNA is wrapped around histones, …

Biochemical Journal, 87(2), 258–263. doi:10.1042/bj0870258 Webb31 okt. 2024 · Acetyl groups are also often added to histones and other proteins, modifying their properties. For example, histone acetylation by histone acetyltransferases (HATs) causes an expansion of chromatin architecture on the DNA level, allowing for genetic transcription to occur.

Webb31 mars 1998 · It has long been recognized that a correlation exists between acetylation of lysines in the core histones and states of transcription (1–4).More recently it has become apparent that the N ɛ-acetylation of highly conserved lysines on the amino-terminal tails of histones is associated with a variety of cellular processes, including the deposition of …

Histone lysine demethylating events are influenced by the elevated levels of succinate and fumarate that are associated with metabolic rewiring of trained macrophages.
WebbHistone deacetylases remove the acetyl groups from histones. This leads to formation of the transcriptionally inactive heterochromatin, in which gene expression is hindered. To maintain the transcriptionally active state of chromatin, HATs and HDACs should work together [ 23 , 24 , 25 ].
