Amine for the top: A biocatalyst able to perform transamination of less hindered ketones is modified to transform a sterically demanding ketone substrate to the corresponding optically pure amine. This goal is achieved by rational analysis and design of the catalyst’s structure as well as other techniques of directed evolution. The biocatalyst is successfully adapted to the process and not vice versa.
