[Identification of an essential glutamate residue in the 3-phosphoglycerate kinase of yeast].
The incorporation of nitrotyrosine into 3-phosphoglycerate kinase activated by carbodiimide results in the chemical modification of a single essential residue. After total proteolytic digestion, isolation of the dipeptide gamma Glu-NO2 Tyr by immuno-affinity chromatography indicates the implication of a glutamyl residue. It is interesting to point out the applicability of the method described for the purification of peptides containing carboxyl residues.
