Recently new lysine modifications were detected in histones and other proteins. Using the pyrrolysine amber suppression system we genetically inserted three of the new amino acids ε-N-propionyl-, ε-N-butyryl-, and ε-N-crotonyl-lysine site specifically int

A novel, convenient synthesis, using copper ions, is described for the multigram-scale preparation of acryloyl and methacryloyl ornithine and lysine without the need to use protecting groups and chromatographic purifications. Three methods of removing the

Molecular rotations of N(α)-acyl-L-lysines were determined in water and in water containing various amounts of HCl or NaOH. The acyl groups were formyl, acetyl, propionyl, and butyryl. Each N(α)-acyl-L-lysine exhibited more negative rotation in HCl or NaOH solution than in water. The plot of molecular rotation against amount of HCl or NaOH resembled that of a D-α-amino acid even though N(α)-acyl-lysine was of L-form. The reason for this is discussed from the standpoint of steric factors. N(ε)-Acyl-L-lysines corresponding to the N(α)-acyl-L-lysines were synthesized as reference compounds. It was found that water-soluble N(ε)-acyl-L-lysines can be easily prepared by acylation of the Cu complex solution of L-lysine hydrochloride in the presence of triethylamine. The molecular rotation plots for N(ε)-acyl-L-lysines were typical of L-α-amino acids.
