Abstract excerpt
A mutant human lysozyme P110, in which Val110 was replaced with Pro, was secreted by Saccharomyces cerevisiae; modification of the cysteine residue at position 77 was found in a purified mutant protein (P110-B) upon primary structure analysis. A peptide fragment containing 15 amino acid residues from Thr70 to Leu84 was obtained by proteolytic digestion of the protein and subsequently isolated by reverse-phase...
