INSECTICIDAL MUTANT Av3 POLYPEPTIDES and METHODS FOR PRODUCING and USING

Proteins， nucleotides and insecticidal polypeptides， their expression in the plants， methods for producing the polypeptides， processes， techniques， production of polypeptides， Formulations， synthetic polypeptides， bodies and one process that increases the yield of the production of insecticidal peptides from systems of expression of yeast. The present also relates and refers to toxins are called AVP， which are modified from the Av3 toxin of the obtained anémona of sea; in the present Describe the genes that encode the polypeptide， as well as various formulations and combinations thereof; both of genes as of peptides， useful for the control of insects. Claim 1: One AVP which has insecticidal activity against one or more species of insects， where the AVP has to the less one of the following mutations: to) An N-terminal mutation that replaces the arginine to aminoterminal with one amino acid lysine (R1K) in connection with the SEQ ID no: 1， b) deletion of one amino acid valine C - Terminal in relation with the SEQ ID no 1.
