Hat transferase
WebHAT. One member of particular interest in the family of acyltransferases is the group of histone acetyltransferases (HATs; EC 2.3.1.48). Enzymes of this kind acetylate core … Histone acetyltransferases (HATs) are enzymes that acetylate conserved lysine amino acids on histone proteins by transferring an acetyl group from acetyl-CoA to form ε-N-acetyllysine. DNA is wrapped around histones, and, by transferring an acetyl group to the histones, genes can be turned on and off. In … See more HATs are traditionally divided into two different classes based on their subcellular localization. Type A HATs are located in the nucleus and are involved in the regulation of gene expression through acetylation of nucleosomal histones See more The basic mechanism catalyzed by HATs involves the transfer of an acetyl group from acetyl-CoA to the ε-amino group of a target lysine side-chain within a histone. Different families of … See more The catalytic activity of HATs is regulated by two types of mechanisms: (1) interaction with regulatory protein subunits and (2) … See more Chromatin remodeling Histone acetyltransferases serve many biological roles inside the cell. Chromatin is a combination of proteins and DNA found in the nucleus, and it undergoes many structural changes as different cellular events such as See more In general, HATs are characterized by a structurally conserved core region made up of a three-stranded β-sheet followed by a long α-helix parallel to and spanning one side of it. The core … See more The structures of several HAT domains bound to acetyl-CoA and histone substrate peptides reveal that the latter bind across a groove on the protein that is formed by the central core region at the base and is flanked on opposite sides by the variable N- and C-terminal … See more Histone acetyltransferases (HATs) and histone deacetylases (HDACs) are recruited to their target promoters through physical interactions with sequence-specific transcription factors. They usually function within a multisubunit complex in which the other … See more
