alpha-Amylase inhibitors from wheat: amino acid sequences and patterns of inhibition of insect and human alpha-amylases.


Four alpha-amylase inhibitors, WRP24, WRP25, WRP26, and WRP27, were purified from wheat flour by preparative, reversed-phase high performance liquid chromatography. All have polypeptide molecular masses of about 14 kDa and are members of the cereal superfamily of protease and alpha-amylase inhibitors. Sedimentation velocity analysis indicated that WRP25 and… (More)
