Abstract
The vitelline coat lysin of a top shell, Tegula pfeifferi, is a single polypeptide consisting of 118 amino acid residues and having a relative molecular mass of 13,800. The complete amino acid sequence of the vitelline coat lysin was determined by the analyses of five peptides obtained by cyanogen bromide degradation and three fragments obtained by Staphylococcus aureus protease digestion of the protein. The sequence showed the presence of microheterogeneities in the vicinity of the C-terminal half of the molecule and the existence of two homologous domain structures.
