In 2012, David Rozzell published an excellent and concise survey of commercial enzyme suppliers. This chapter includes details of companies that provide one or more of the many services focused towards bioprocess development. This survey is primarily aimed at the industrial and academic synthetic chemist who needs to source enzymes or services for biocatalytic process development. The chapter presents a table regarding commercial enzyme suppliers and distributors, providing information on enzyme name, supplier, company contact details, and attributes. It also presents a table that gives details on bioprocess service providers, providing company name and website. The chapter includes a list of the chemical transformations of selected commercially available enzymes.
