FunFam 5616: Histone H3 type 1

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Histone acetyltransferase. [EC: 2.3.1.48]
Acetyl-CoA + [protein]-L-lysine = CoA + [protein]-N(6)-acetyl-L-lysine.
  • A group of enzymes acetylating histones.
  • Several of the enzymes can also acetylate lysines in other proteins.

[Histone H3]-lysine-36 demethylase. [EC: 1.14.11.27]
(1) Protein N(6),N(6)-dimethyl-L-lysine + 2-oxoglutarate + O(2) = protein N(6)-methyl-L-lysine + succinate + formaldehyde + CO(2). (2) Protein N(6)-methyl-L-lysine + 2-oxoglutarate + O(2) = protein L-lysine + succinate + formaldehyde + CO(2).
  • Of the seven potential methylation sites in histones H3 (K4, K9, K27, K36, K79) and H4 (K20, R3) from HeLa cells, the enzyme is specific for Lys-36.
  • Lysine residues exist in three methylation states (mono-, di- and trimethylated).
  • The enzyme preferentially demethylates the dimethyl form of Lys-36 (K36me2), which is its natural substrate, to form the monomethyl and unmethylated forms of Lys-36.
  • It can also demethylate the monomethyl- but not the trimethyl form of Lys-36.

Histone-lysine N-methyltransferase. [EC: 2.1.1.43]
S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone].
