Amino acid sequence of sialic acid binding lectin from frog (Rana catesbeiana) eggs

Abstract

The complete amino acid sequence of sialic acid binding lectin from frog (Rana catesbeiana) egg is presented. The 111-residue sequence was determined by the analysis of peptides generated by digestion of the S-carboxymethylated protein with Achromobacter protease I, chymotrypsin, or cyanogen bromide. The sequence is unique and not homologous to any known protein sequence. The protein may represent a new type of lectin.
