Global histone acetylation
WebHistone acetyltransferases (HATs) catalyze the acetylation of lysines within the N-terminal tails and globular domains of histone proteins by transferring an acetyl group using acetyl-CoA as a substrate. By this modification, histones form transcriptionally active euchromatin structure, enabling active gene expression [1,2,3,4]. These HATs are ... WebJun 11, 2004 · Understanding the association of various histone acetylation sites with gene activity requires a global view of the acetylation patterns of individual lysines. Here, …
