Transglutaminase: Fundamentals and Applications, a new volume in the Foundations and Frontiers in Enzymology series, stands as a comprehensive resource on this increasingly important class of enzymes. Following an introduction to the field, international experts discuss basic biology and structure – function relationships of transglutaminases, ongoing fundamental research, and new application areas, including food processing, material synthesis, biomedicine, disease treatment, and biotechnology. Approaches for sourcing transglutaminases from animals, plants, and microorganisms are considered, followed by chapters on applied uses in biomedicine, skin, bone biology, medicine, drug development, tissue engineering, seafood bioprocessing, dairy bioprocessing, synthesis of materials and polymers, and as an immobilization agent. Research protocols are also provided, including research rationale, design, substrates, assays, and microassay steps for studying transglutaminases.
