  研究进展

  课题组利用高速原子力显微镜研究了昆虫GH18家族几丁质酶混合物在结晶几丁质表面水解过程中影响其进程性的关键因素。

  在单分子水平上,我们发现内切性几丁质酶OfChtI和OfChtII有助于提升外切酶OfChi-h在结晶几丁质水解中的进程性能力,显著增加每个几丁质酶新结合到几丁质表面积单位上的OfChi-h的数量,增加OfChi-h分子在几丁质表面上进程性运行的持续时间。我们发现当有内切性几丁质酶存在时,OfChi-h分子聚集在几丁质纤丝的末端并形成簇,迅速消融几丁质纤维丝。OfChi-h对底物的结合与络合影响了其进程性水解。根据OfChi-h分子在几丁质原纤维上的排列行为,我们推断出进行性启动的时间为0.22±0.07 s。这项工作提高了我们在结晶几丁质水解的固液界面催化过程中对内切几丁质酶协同作用的认识,突出了内切几丁质酶在促进进行性水解中的作用。该项工作发表于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.

  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.
