In vitro analysis of the digestive enzymes amylase and α-glucosidase in the midguts of Locusta migratoria L. in response to the myosuppressin, SchistoFLRFamide

We suggest that the minimum amino acid sequence in SchistoFLRFamide necessary to increase both amylase and α-glucosidase activity is DHVFLRFamide. We have determined that two other peptides endogenous to the locust, AFIRFamide and GQERNFLRFamide, increase amylase and α-glucosidase activity in midgut lumen contents.
