Research Interests

Focusing on key proteins in the process of marine life, mainly with biochemical and biophysical techniques, to elucidate the assembly and catalytic mechanism of key proteins (enzymes) at molecular level, laying the basic understanding for the decoding of blue life. On this basis, combined with genetic engineering, enzyme engineering, and other bioengineering technology, to carry out the industrialization of key proteins (enzymes) application research, break through the technical bottleneck of the industrialization of marine biological protein resources, to help the high value of marine biological protein resources. The team's main focus is currently:

1.Degradation mechanism of marine complex polysaccharide degrading enzymes.

2. Assembly mechanism of scallop byssal proteins.

Research Project

The research team has undertaken and participated in more than 10 national and provincial-level projects, 2 projects of the Science and Technology Commission of the Central Military Commission. In the past 5 years, more than 20 SCI articles have been published in internationally renowned academic journals such as Bioactive Materials, Acta Crystallographica Section D: Economic Biology,Biochim Biophys Acta Gen Subj. Applied for 15 invention patents, 7 authorized patents, and 1 transferred patent. Chaired the preparation of 3 monographs.

In terms of marine oligosaccharide tool enzymes. In order to find homogenous algal oligosaccharide tool enzymes to meet the industrial demand, the structure-activity relationship of algal oligosaccharide lyase sequence and product distribution was established, and tool enzyme which can be used to prepare alginate oligosaccharides (AOs) with specific degree of polymerization was successfully obtained.

In terms of marine biological adhesive proteins. With the goal of exploring the active adhesive protein material, multiple omics technology was utilized to obtain a variety of new marine life wet adhesive materials, the new adhesive material assembly mechanism and preclinical application research have been carried out systematically, laying the foundation for the development of high-quality medical biological materials with independent intellectual property rights.
