HistoneH3 (1-25), amide is a N-terminal peptide fragment of histoneH3 that serves as a substrate for histone methyltransferases (HMTs). It can be utilized to identify the substrate for HMTs. Compared to histoneH3 (15-39) and full-length histoneH3, HistoneH3 (1-25), amide proves to be more efficient as a substrate for HMT G9a.
HistoneH3 (1-35) is a 35-residue peptide derived from histoneH3, which is a key member of the five main histones participating in the formation of chromatin within eukaryotic cells.
HistoneH3 (21-44), derived from a sequence of 21-44 amino acids of histoneH3, is commonly employed as a substrate, particularly for protein arginine methyltransferase assays, where methylation activity is being examined.
HistoneH3 (1-21) is a truncated form of the HistoneH3 protein consisting of amino acids 1 to 21. It serves as a common substrate for methyltransferase assays targeting Histone 3 at lysine 4 and lysine 9, as well as for acetyltransferase assays targeting Histone 3 at lysine 9 and lysine 14.
HistoneH3 (23-34) is a peptide consisting of amino acid residues 23 to 34 of the histoneH3 protein. This peptide specifically includes lysine residues at positions 23 and 27, which can undergo methylation and acetylation modifications.
