Folding of DNA into chromatin is mediated by binding tohistones such as H4; association of DNA with histones isregulated by covalent histone modifications,e.g. acetylation,methylation,andbiotinylation.We sought to identifyamino-acid residues that are biotinylated in histone H4,and todetermine whether acetylation and methylation of histonesaffect biotinylation. Synthetic peptides spanning fragmentsof human histone H4 were biotinylated enzymatically usingbiotinidase. Peptide-bound biotin was probed with strept-avidin–peroxidase....
