Abstract A peptide which stimulates the contractile activity of the cockroach hindgut was isolated from head extracts of the cockroach, Leucophaea maderae. The inability of aminopeptidase M to degrade the peptide and the presence of glutamic acid in the hydrolysate suggested N-terminal blocking by pyroglutamic acid. The N-terminal pGlu was removed enzymatically and the unblocked fragment was sequenced with an automated gas-phase peptide sequencer. The structure determined (pGlu-Thr-Ser-Phe-Thr-Pro-Arg-Leu-NH2) was synthesized and shown to be both chemically and biologically identical with the natural product.
