In addition to performing its prime function as a vehicle for scientific communications of varied colora tions, Molecular and Cellular Biochemistry is again focusing on two subjects which it treats in depth. One of these is a book issue dealing with the transglutaminase reaction. The other is this issue that deals with induction and modulation of enzymes. This is a very broad subject that calls for broader coverage than could be included in one book issue. However, I have elected to include only certain contributions that serve as general examples of the principles involved. There are six...

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...
