This invention provides a method for preparing and applying a controlled-release agent of emamectin benzoate, belonging to the field of nanopesticide technology. This invention uses PFC-1, a hydrogen-bonded organic framework material with a porous structure, as a drug carrier. After loading emamectin benzoate through its porous structure, the loaded system is further modified by surface encapsulation with sodium lignosulfonate. The resulting nano-formulation with controlled-release function is called emamectin benzoate nano-controlled-release agent. The prepared drug-loaded system exhibits good insecticidal activity against diamondback moth. The preparation method includes a method for preparing emamectin benzoate-loaded agents. The prepared system has a high loading capacity of 19.6%. The drug-loaded system provided by this invention has good insecticidal effect against diamondback moth and exhibits pH-selective release effect in the midgut environment of the diamondback moth.

The present application relates to the technical field of step-by-step synthesis reaction, in particular to a step-by-step synthesis reaction method of emamectin benzoate, which extracts the heat trace path of raw materials in the preheating section and forms a propulsion trajectory line, selects a related heat band in the middle section to generate a conversion path diagram, positions each path and connects the conversion fluctuation section to form a rhythm structure, reflects the main and auxiliary material route adjustment entrance to realize collaborative propulsion, and connects the whole section to form a synthesis path paragraph set along the propulsion direction. The present application can form a comparable spatial clue by converting the heat diffusion change of the raw material after touching the wall into a path sequence, continuously track the reaction progress by observing the energy fluctuation and position change of the path in the middle section, present the stage connection rhythm by associating the start and end points of each path section, and facilitate the identification of the transition urgency. By comparing the main and auxiliary material paths, the approach area deviation can be captured to improve the consistency of the entry section. By integrating all path sections along the propulsion direction, the continuous coupling of multi-section reactions can be enhanced and the deviation can be reduced.

The invention provides a construction method and application of a P450 fusion protein. The construction method comprises the following steps: step (1), fusing abamectin oxidation type P450 Ema1 with a Rhodococcus P450RhF-RPs reductase structural domain by adopting a connecting peptide to obtain Ema1-Rhf; and (2) carrying out point mutation on the Ema1-Rhf, and constructing the P450 fusion protein. According to the invention, redox partners derived from Rhodococcus are connected with a structural domain of P450 Ema1 through a designed connecting peptide; the cytochrome P450 monooxygenase mutant further improves the enzyme activity in the process of catalyzing abamectin to be converted into methylamino abamectin, the maximum conversion rate can be improved by 2.2 times through determination, and the mutant achieves 90% conversion rate within 39.8 hours, which is far better than the expression of an unfused system. And the method has certain significance on industrial production of the emamectin benzoate.
