The VIIth International Conference on Aspartic Proteinases was held in Banff, Alberta, Canada, from October 22 to 27, 1996. The venue was the Banff Centre in the Canadian Rockies, a setting well known worldwide for the scenic beauty and mountain grandeur. It was perhaps presumptuous of the organizers to call this the seventh Aspartic Proteinase Conference but it was felt that the meeting in 1982, organized by Tom Blundell and John Kay, was of an international stature and covered topics sufficiently broad to constitute a conference. Thus, there is a discontinuity in that the Gifu Conference organized by Prof. Kenji Takahashi was the fifth International Conference on Aspartic Proteinases. Officially, there has not been a sixth Conference and if there is confusion, it is the result of my desire to recognize the importance of the London meeting. Banffhosted 106 scientists from 14 different countries. There were 26 invited speak ers among the 44 oral presentations of the 7 main sessions. In addition, there were 53 con tributed poster presentations that spanned the whole range of interest in aspartic proteinases.

This volume introduces the reader to the field of enzyme stabilization and the different theories of enzyme stabilization, including the use of immobilization as a stabilization technique.

The objective of the Springer Handbook of Enzymes is to provide in concise form data on enzymes sufficiently well characterized. Data sheets are arranged in their EC-Number sequence. Each volume comprises one enzyme class, sometimes the enzyme classes have to be divided into several volumes. Considerable progress has been made in enzymology since the publication of the first edition (published as "Enzyme Handbook): many enzymes are newly classified or reclassified. In the 2nd edition each entry is correlated with references and one or more source organisms. New datafields are created: "application" and "engineering" (for the properties of enzymes where the sequence has been changed). Altogether the amount of data has doubled so that the 2nd edition will consist of approx. 25 volumes. This collection is an indispensable source of information for researchers in biochemistry, biotechnology, organic and analytical chemistry, and food sciences.

This book describes the reaction rate profiles of the -galactosidase-catalyzed conversion of lactose on the inner surface of a hollow fiber membrane, which is employed as an enzymatic reactor system. The reaction rate profiles were obtained by solving the mass transfer and kinetics of reaction in a 2-dimensional model of the system. The primary challenge of this research was to develop the kinetic model of the reaction to describe the kinetic behavior as the reaction occurred on the membrane surface. Despite the difficulties, the proposed model can reliably replicate the actual process, as validation procedures have confirmed. The reaction rates obtained analyze the performance of the immobilized enzyme on the membrane surface. Previously, an increase in performance of ' -galactosidase-catalyzed conversion of lactose assisted by ultrafiltration was suggested due to inhibitor removal. However, as the analysis presented here shows, the concentration profile of the substrate on the membrane surface also affects the reaction performance.

The kinetic mechanisms by which enzymes interact with inhibitors and activators, collectively called modifiers, are scrutinized and ranked taxonomically into autonomous species in a way similar to that used in the biological classification of plants and animals. The systematization of the mechanisms is based on two fundamental characters: the allosteric linkage between substrate and modifier and the factor by which a modifier affects the catalytic constant of the enzyme. Combinations of the physically significant states of these two characters in an ancestor-descendant-like fashion reveal the existence of seventeen modes of interaction that cover the needs of total, partial and fine-tuning modulation of enzyme activity. These interactions comprise five linear and five hyperbolic inhibition mechanisms, five nonessential activation mechanisms and two hybrid species that manifest either hyperbolic inhibition or nonessential activation characteristics depending on substrate concentration. Five essential activation mechanisms, which are taxonomically independent of the mentioned basic species, complete the inventory of enzyme modifiers. Often masked under conventional umbrella terms or treated as anomalous cases, all seventeen basic inhibition and nonessential activation mechanisms are represented in the biochemical and pharmacological literature of this and the past century, either in the form of rapid or slow-onset reversible interactions, or as irreversible modification processes. The full potential of enzyme inhibitors and activators can only be appreciated after elucidating the details of their kinetic mechanisms of action exploring the entire range of physiologically significant reactant concentrations. This book highlights the wide spectrum of allosteric enzyme modification in physiological occurrences as well as in pharmacological and biotechnological applications that embrace simple and multiple enzyme-modifier interactions. The reader is guided in the journey through this still partly uncharted territory with the aid of mechanistically-oriented criteria aimed at showing the logical way towards the identification of a particular mechanism.

Yeasts are a versatile group of eukaryotic microorganisms, exhibiting heterogeneous nutritional profiles and an extraordinary ability to survive in a wide range of natural and man-associated ecosystems, including cold habitats. Cold-adapted yeasts inhabit numerous low-temperature environments where they are subjected to seasonal or permanent cold conditions. Hence, they have evolved a number of adaptation strategies with regard to growth and reproduction, metabolic activities, survival and protection. Due to their distinctive ability to thrive successfully at low and even subzero temperatures, cold-adapted yeasts are increasingly attracting attention in basic science and industry for their enormous biotechnological potential.

This book presents our current understanding of the diversity and ecology of cold-adapted yeasts in worldwide cold ecosystems, their adaptation strategies, and their biotechnological significance. Special emphasis is placed on the exploitation of cold-adapted yeasts as a source of cold-active enzymes and biopolymers, as well as their benefits for food microbiology, bioremediation and biocontrol. Further, aspects of food biodeterioration are considered.
