Primal structure and activity studies of allatostatin 4 (AST 4)

The juvenile hormones (JH) are critical to the contro1 of insect development andreproduction. The production of JH by the corpora allata (CA) is regulatd in part bypeptides originating from brain. One group of these peptides termed allatostatins (AST)reversibly inhibits the biosynthesis of JH invitro. The correlation of these events suggeststhat AST, i.e. their biosynthesis, are important in the regulation of JH biosynthesis.
