| Isolation and Identification of Peptidic a-Glucosidase Inhibitors Derived from Sardine Muscle Hydrolyzate  | | | | Abstract
| We report here the isolation of a-glucosidase (A G H) inhibitory peptides derived from sardine muscle hydrolyzate, which was prepared by digestion with Bacillus licheniformis alka line protease. A s a result of reversed-phase HPLC purification, two A G H inhibitory peptides were isolated from a D EA E -Sephadex A-25 column eluate. The peptides were identified as follows: V al-Trp (IC50 = 22.6 mM) and T ry -T y r -P r o -L e u (IC50 = 3.7 mM). A G H inhibitory studies of T r y -T y r -P r o -L e u and its derivatives demonstrated the importance of the tri peptide chain length as well as the hydrophobic aromatic amino acid tyrosine at the N-terminus, aliphatic amino acids at the C-terminus, as well as an amide proton from the peptide chain at the middle position of the tri-peptide to develop AGH inhibition activity. | | | |
