This book contains most of the papers presented . at the Second International Symposium on Intracellular Protein OItaboiism, which was held on May 26-30,1975 in Ljubljana, Yugoslavia. The papers presented in this book cover a wide variety of areas related to protein turnover and responsible enzymes. The symposium attracted about one hundred parti­ cipants, and the cordial atmosphere, the frank discussions and the exchange of ideas were a stimulant for all those attending_ During the last decade, investigations in the wide field of intracellular protein catabolism have been rapidly taken up in many laboratories, because the mechanisms and regulation of degradative processes are rather less studied compared to synthetic processes. In view of this increased interest, Prof. H. Hanson and his coworkers organized the First Interna­ tional Symposium and the papers presented there were published in the book Intracellular Protein Catabolism, edited by H. Hanson and P. Bohley. In the preface of this book they concluded: "We hope, however, the symposium as well as the book will be the beginning of a series of symposia and their publication concerning intracellular protein catabolism. " We would like to express our thanks for financial support provided by the Research Council of Slovenia. Special thanks are due to the organizing committee of the symposium, and to Dr. I. Kregar and particularly Dr. J. Babnik for their efforts in preparing manuscripts for the publishers.
