  研究進(jìn)展

  課題組利用高速原子力顯微鏡研究了昆蟲GH18家族幾丁質(zhì)酶混合物在結(jié)晶幾丁質(zhì)表面水解過(guò)程中影響其進(jìn)程性的關(guān)鍵因素。

  在單分子水平上,我們發(fā)現(xiàn)內(nèi)切性幾丁質(zhì)酶OfChtI和OfChtII有助于提升外切酶OfChi-h在結(jié)晶幾丁質(zhì)水解中的進(jìn)程性能力,顯著增加每個(gè)幾丁質(zhì)酶新結(jié)合到幾丁質(zhì)表面積單位上的OfChi-h的數(shù)量,增加OfChi-h分子在幾丁質(zhì)表面上進(jìn)程性運(yùn)行的持續(xù)時(shí)間。我們發(fā)現(xiàn)當(dāng)有內(nèi)切性幾丁質(zhì)酶存在時(shí),OfChi-h分子聚集在幾丁質(zhì)纖絲的末端并形成簇,迅速消融幾丁質(zhì)纖維絲。OfChi-h對(duì)底物的結(jié)合與絡(luò)合影響了其進(jìn)程性水解。根據(jù)OfChi-h分子在幾丁質(zhì)原纖維上的排列行為,我們推斷出進(jìn)行性啟動(dòng)的時(shí)間為0.22±0.07 s。這項(xiàng)工作提高了我們?cè)诮Y(jié)晶幾丁質(zhì)水解的固液界面催化過(guò)程中對(duì)內(nèi)切幾丁質(zhì)酶協(xié)同作用的認(rèn)識(shí),突出了內(nèi)切幾丁質(zhì)酶在促進(jìn)進(jìn)行性水解中的作用。該項(xiàng)工作發(fā)表于ACS Catalysis.

 

  PI

  Qing Yang, a principal investigator at the Institute of Agricultural Genomics Institute at Shenzhen, Chinese Academy of Agricultural Sciences. She has made pioneer contributions to the development of novel pesticide molecular targets that are highly effective and safe for both humans and animals. Her major research interests include: 1) discovering new pesticide targets, specifically key proteins involved in chitin-associated bioprocesses such as chitin biosynthesis, degradation, and assembly in insect pests and phytopathogens of agricultural significance, and 2) developing small molecules to target these proteins. The ultimate goal of her work is to control insect pests, nematodes, and phytopathogens of agricultural importance in a human-safe, eco-friendly, and efficient manner.

  Research Interest

  Our research fields include: I. Molecular mechanism of insect epidermis and exoskeleton formation; II. Structural biology study and inhibitor design of key proteins of agricultural pests development; III. Molecular regulation of agricultural pests and plant diseases.

  The research projects undertaken by our group in 2020 include: 1 NSFC key project, 2 NSFC Youth Foundations, and 2 Postdoctoral Science Foundations. We published 10 papers in 2020, including 2 papers with impact factors greater than 10. Two postdocs finished their research work.

 

  Major Achievements

  We employed HS-AFM to investigate the factors that affect processivity using an insect GH18 chitinase cocktail during the interfacial enzymatic hydrolysis of crystalline chitin.

  At the single molecule level, we have revealed endochitinases (OfChtI and OfChtII) as a significant factor to elevate the processivity of OfChi-h in crystalline chitin hydrolysis, to dramatically increase the number of OfChi-h newly bound onto a chitin surface area unit per chitinase concentration, and to increase the duration time of processive running OfChi-h molecules on the chitin surface. In the presence of endochitinases, OfChi-h molecules were observed to crowd at the ends of chitin fibrils and form clusters that quickly ablate chitin fibrils. The processive initiation including initial OfChi-h-substrate binding and complexation is a factor that affects processive hydrolysis. The time for processive initiation was deduced to be 0.22 ± 0.07 s according to an aligning behavior of OfChi-h molecules on chitin fibrils. This work improves our knowledge of exo?endo chitinase synergism during the solid?liquid interfacial catalysis of crystalline chitin hydrolysis, highlighting the role of endochitinases in boosting processive hydrolysis. This work was published in ACS Catalysis.
