Abstract

The complete amino acid sequence of a sweet-taste-suppressing peptide, gurmarin, from the leaves of Gymnema sylvestre was determined by the Edman analysis of peptides derived from digests obtained with Staphylococcus aureus V8 protease, pyroglutamyl aminopeptidase, and lysyl endopeptidase. Gurmarin consists of 35 amino acid residues with an amino-terminal pyroglutamyl residue and has the molecular weight of 4,209. Gurmarin has no significant homology with other known proteins.
