The model peptide glycylglycylaspartylalanine was phosphorylated in the NMR sample tube and characterized by 31P NMR spectroscopy. The pK,, value of the acyl phosphate group in glycylglycyl(/l-aspartyl phosphate)alanine was determined to be 4.6 and the chemical shift was -6.45 ppm at low pH (1.5) an
