MYST Histone Acetyltransferases (HAT), a diverse family of proteins responsible for a variety of functions in eukaryotes from yeast to humans<ref>PMID:11134336</ref>. These particular histone acetyltransferases are part of the MYST family because of their structure which includes <scene name='78/782639/Coenzyme_a/1'>coenzyme A</scene> and <scene name='78/782639/Zinc_ion/1'>Zinc Ion</scene>.  
You may include any references to papers as in: the use of JSmol in Proteopedia <ref>DOI 10.1002/ijch.201300024</ref> or to the article describing Jmol <ref>PMID:21638687</ref> to the rescue.


== Function ==
== Function ==
Highly conserved in eukaryotes, their key roles in post-translation modification of histones. Profound effect on chromatin structure in eukaryotes. Composed of an Acetyl-CoA binding motif and a zinc finger. The enzyme looks for lysine residues which are the universal target for acetylation, and by the addition of an acetyl group stablilizes the electrons of a histone making them less positively charged.
== Relevance ==
These enzymes acetylate lysine amino acids of histone by transferring the acetyl group of acetyl CoA to form N-acetyllysine. While the DNA coiled around histones and the activity of histone acetyltransferase is able to turn genes on or off, along with influencing gene expression by acetylating non-histone proteins<ref>PMID:10441070</ref>.


== Disease ==
== Disease ==
HATs activate the residues of p53 by acetylation which leads to the elevation of p53 DNA binding or loss of its transcriptional activity<ref>PMID:10441070</ref>. If there’s any type of mutation where acetylation occurs of the p53 residues the functionality is hindered leading to the growth of tumors/cancers.

{{Template:ColorKey_N52C3Rainbow}}<scene name='78/782639/N_to_c_rainbow/1'>N to C Sequence</scene>
The binding site for this structure <scene name='78/782639/Coenzyme_a/3'>coenzyme A</scene>, which is involved in the transfer of an acetyl group from acetyl-CoA to the amine group of a lysine residue. The <scene name='78/782639/Zinc_ion/1'>zinc</scene> finger region of this structure is involved in the acetyltransferase activity and chromatin binding of the histone. The <scene name='78/782639/Cysteine_rich_structure/1'>cysteine</scene> residues are needed for catalyzing specific acetylation.
