摘要：

A diuretic peptide (Acheta-DP) has been isolated from extracts of whole heads of the house cricket, Acheta domesticus. The native peptide increases both cyclic AMP production and the rate of fluid secretion by isolated Malpighian tubules in vitro to an extent comparable with those responses obtained with supra-maximal amounts of crude extracts of corpora cardiaca. The primary structure of Acheta-DP was established as a 46-residue amidated peptide: TGAQSLSIVAPLDVLRQRLMNELN-RRRMRELQGSRIQQNRQLLTSI-NH2. Acheta-DP has 41% sequence identity with a diuretic peptide isolated from Manduca sexta, providing direct evidence for the presence of a family of diuretic peptides in insects.
