Patent number: 11884954Abstract: A protein complex based on DNA enzymes of an E family of Escherichia coli and an application thereof in artificial protein scaffolds are provided. The protein complex includes one or more of interaction pairs formed by a CL2 protein and an Im2 protein, a CL7 protein and an Im7 protein, a CL8 protein and an Im8 protein, or a CL9 protein and an Im9 protein. By protein engineering of a carboxyl terminus DNase domain of the DNA enzymes CE2, CE7, CE8 and CE9, mutants that lose DNA enzyme activity but still retain the ultra-high affinity with the corresponding Im protein are obtained, and protein interaction pairs CL2/Im2, CL7/Im7, CL8/Im8 and CL9/Im9 are constructed. These protein interaction pairs have properties of heat resistance, high affinity, high specificity, small molecular weight, fast assembly speed, etc. Based on this, an artificial protein scaffold is constructed for the construction of artificial multienzyme complexes.Type: GrantFiled: December 29, 2022Date of Patent: January 30, 2024Assignee: Hubel UniversityInventors: Lixin Ma, Chao Zhai, Jun Yang, Fei Wang
