CHITINASE PRODUCING AND SECRETING VECTOR

摘要

Engineered DNA is disclosed encoding a pre-protein which comprises a Streptomyces chitinase signal sequence and a desired mature protein. Preferably, the signal sequence is from the S. plicatus endochitinase gene. The engineered DNA is included in a host organism causing the host to produce and secrete the mature protein. Where the mature protein is a chitinase, the invention can be applied to the control of chitinase-sensitive pests.
