Even a casual search of recent literature would show that the involvement of transglutaminases in a great variety of biological reactions has captured the imagination of many investigators. The present volume of Molecular and Cellular Biochemistry is a reflection of this growing interest. Transglutaminases catalyze the post-translational modification of proteinbound glutamine residues which either causes protein cross-linking by 'Y-glutamyl-e-Iysine peptide bridges or covalent incorporation of small molecular weight amines. These reactions could have far-reaching effects on altering the...
