研究方向

1、酶的结构生物学与生物信息学

借助结构生物学和生物信息学技术深入研究重要工业酶的序列、结构和功能关系，在对酶蛋白三维空间结构进行解析的基础上，通过对酶蛋白进行构效解析、理性设计和定向进化，提出理性设计和定向进化策略来生产新型和改良工业酶。

2、精细化学品的生物催化与转化

开展工业生物催化剂及其催化过程的研究，采用酶或全细胞催化技术，生产化学法难以转化与合成的新型生物产品，或替代现行化学合成工艺中的复杂步骤。研究生物体及其酶进行定向物质转化的分子机制，开发新的生物合成技术。开发化工原料、医药原料、手性化合物、功能糖与糖基化学品等高值精细化学品的高效生物合成技术，以生物技术改造化学工业过程。
