Course objectives

At the end of the course students should know principles of protein structure and function. In the first part, individual structural motifs recurring in protein structures are described, and ways are shown how proteins with quite unrelated functions are built up from combinations of these. In the second part, particular biological functions are considered and the different protein structural solutions are discussed that have evolved to fulfill them. In the third part, the basic techniques of protein structural biology are introduced and examples of engineering protein structure and function are shown.

Syllabus

1. Basic structural principles of protein architecture. The building blocks of proteins. Motifs of protein structure. Domain structure of proteins. 2. The roles of individual motifs of protein structure in protein biological functions. DNA interacting proteins, transcription factors, receptors. Molecular recognition of foreign molecules by immune system. Membrane proteins, membrane receptors. Enzyme catalysis. Prediction, engineering, and design of protein structures. Determination of protein structure. 3. Genetic engineering techniques for structure-function analysis in proteins. Recombinant DNA construction. Gene isolation and cloning. Gene expression regulating elements. DNA sequencing. In vitro mutagenesis. Recombinant protein production in heterologous expression systems.
