摘要：

A myotropic peptide, termed Lom-AG-myotropin, was isolated from extracts of 4400 accessory gland complexes of males of the locust, Locusta migratoria; the following sequence was derived: Gly-Phe-Lys-Asn-Val-Ala-Leu-Ser-Thr-Ala-Arg-Gly-Phe-NH2. This sequence is completely different from all presently known myotropic peptides from Locusta or other insects. The Lom-AG-myotropin is active on the oviduct and hindgut of Locusta migratoria and Leucophaea maderae. The stimulatory activity is, in both insects, 1000 times greater on the oviduct than on the hindgut, suggesting a specificity for the oviduct.
