Journal club as a supplement to the undergraduate biochemistry laboratory

After purification of lysozyme, our biochemistry students write a research proposal that outlines a strategy for studying this enzyme after alteration by site-directed mutagenesis. Despite a literature search that yielded a wealth of background information, students were often overwhelmed by the assignment because they were not familiar with advanced techniques of protein analysis. We therefore developed a series of journal clubs in which teams of students present methods and data found in papers dealing with lysozyme. The five topics for journal clubs include; substrate binding and mechanism; spectroscopic techniques; stability analysis; two-dimensional NMR; and X-ray crystallography. After the adoption of the group talks, the quality of the research proposals improved immensely and students found the assignment to be an educationally rewarding exercise.
