The primary chemical structure of human milk lysozyme: establishment of a temporary formula

Abstract

AbstractThe detailed primary sequences of the N‐terminal moiety (72 amino acid residues) and of the C‐terminal end (23 amino acid residues) of human milk lysozyme (129 residues) are reported. A tentative complete structure of the enzyme is compared to hen and duck egg‐white lysozymes which are very near related proteins despite many amino acid replacements (around 50), the insertion of an additional residue in the N‐terminal and a deletion in the C‐terminal moiety.
