This peptide is histone H4, amino acids 1 to 21. It is acetylated at Lys-8 and at the N-terminus with a C-terminus GG linker, followed by a biotinylated lysine. The acetylation of histone H4 causes structural changes that amplify the binding of transcription factors to their recognition sites within the nucleosome.
