We report on secretion of phospholipase A 2 (PLA 2 ) by in vitro preparations of midguts isolated from tobacco hornworms, Manduca sexta. This enzyme is responsible for hydrolysis of fatty acids from the sn-2 position of phospholipids, a necessary step in fatty acid absorption. The in vitro midgut pr

The molting fluid of pharate adult Manduca sexta was found to contain at least two types of proteinase inhibitor activities. One inhibited the native cuticle degrading trypsin-like proteinase, MFP1, while the other was found to be highly specific for subtilisin-like enzymes. The developmental profil
During the last larval instar of Manduca sexta (tobacco hornworm), the insect enters the wandering phase, in which the animal ceases feeding and the structural reorganization of the midgut begins. Midgut metabolism and ion transport in midguts of feeding and wandering (day 5) fifth-instar tobacco ho
