A) LC/CID/MS/MS of the (M+2H)2+ ion of m/z 822.2 corresponding in mass to the N-terminal monophosphorylated acetylated histone H1.01 tryptic peptide. B) N-terminal 30 residues of avian histone proteins for which sites of phosphorylation were determined. Amino acids in bold indicate residues in which a site of phosphorylation was confirmed. Underlined amino acids indicate residues in which the site of phosphorylation could not be unequivocally assigned.
