Title: The Innovations of Cunzheng Zhang

Introduction

Cunzheng Zhang is a notable inventor based in Jiangsu, China. He has made significant contributions to the field of genetic engineering and biological control, particularly in the development of insecticidal proteins. With a total of 4 patents to his name, Zhang's work has the potential to impact agricultural practices and pest management.

Latest Patents

Zhang's latest patents include a human-derived insecticidal Bt cry toxin mimetic and a design method and application thereof. This invention provides a human-derived molecularly modified insecticidal protein, along with a preparation method and application. The amino acid sequence of the insecticidal protein CCL-CCL_scFv is shown as SEQ ID No. 1. This protein demonstrates significantly higher affinity with midgut BBMV than Cry1Ab toxin, competing with Cry1Ab and Cry1Ac toxins for binding. Through indoor insecticidal biological activity assays, the insecticidal protein shows a good insecticidal effect and can effectively replace Cry1Ac or Cry1Ab toxin for biological control of insect pests. Another patent involves a human-derived insect-resistant gene and an anti-Cry1B toxin idiotype single-chain antibody encoded by this gene. The idiotype single-chain antibody is a β-type and exhibits insecticidal activity, with binding activity to midgut peritrophic membrane specific receptor BBMV.
