Learning objectives:
- To understand the principal characteristics of enzyme activity assays: localization of enzyme, nature of substrate and product, detectable and quantifyable molecules
- Knowledge of factors that influence the detection of a product/byproduct/secondary product of an enzymatic reaction and its link to the genotype

Lecture 8: Enzyme evolution
Learning objectives:
- To understand the drivers of evolution of enzyme activity: mutation and recombination, selective pressure, trade-offs between stability and dynamics
- To describe the acquisition of novel functions and reactivities

Lecture 9 and 10: Technology of library construction
Learning objectives:
