A cDNA encoding a putative precursor of prothoracicotropic hormone (PTTH) from the tobacco hornworm, Manduca sexta, was isolated and sequenced. This clone contains an open reading frame encoding a 226-amino acid prepropeptide hormone. The deduced amino acid sequence is composed of a signal sequence, a precursor domain and a mature hormone and shows similarities to the other PTTHs that have been cloned from closely related lepidopteran species, Bombyx mori, Samia cynthia ricini, Antheraea peryni, and Hyalophora cecropia. The recombinant putative Manduca PTTH produced in E. coli was biologically active, both causing a larval molt in neck-ligated Manduca 4th instar larvae (ED50=50 pM) and the adult molt of diapausing Manduca pupae (ED50=79 pM), but was unable to stimulate molting of debrained Bombyx pupae.
