Credit Hours:
3-0
Pre-requisite:
Computational Chemistry, Biochemistry
Description:
This course combines lectures and laboratory exercises to teach the enzymatic structure and function with
particular emphasis on computational biocatalysis. The course provides a broad understanding of the
theory, with emphasis on the application of computational methods to enzymatic reaction mechanisms.
Laboratory exercises provide hand-on training on practical methods in computational enzymology.
Objectives:
On completion, students will have comprehensive knowledge and understanding of a) the structure and
function of enzymes, b) enzyme kinetics, c) enzymatic reaction mechanisms, d) computational methods in
enzymology and e) the practical knowledge of computational enzymology.
