Hamano, Yoshimitsu (Herausgeber)
Amino-Acid Homopolymers Occurring in Nature
Reihe: Microbiology Monographs 15
Springer-Verlag GmbH, Juli 2010
250 S. - Sprache: Englisch - 235x155x16 mm

ISBN: 3642124526
EAN: 9783642124525

Microorganisms are capable of producing a wide variety of biopolymers. Homopolymer peptides, which are made up of only a single type of amino acid, are far less ubiquitous. The only two amino-acid homopolymers known to occur in nature are presented in this volume. Poly-epsilon-L-lysine is a polycationic peptide and exhibits antimicrobial activity against a wide spectrum of microorganisms. It is both safe and biodegradable and is therefore used as a food preservative in several countries. In addition, there has been great interest in medical and other applications of poly-lysine and its derivatives. In contrast, poly-gamma-glutamic acid is an unusual anionic polypeptide. It is also water soluble, biodegradable, edible, non-toxic and non-immunogenic and can be chemically modified to introduce various drugs. These features are very useful for pharmaceutical and biomedical applications. Poly-glutamic acid is also a highly attractive as a food ingredient.

Marcus, Katrin (Herausgeber)
Quantitative Methods in Proteomics
Reihe: Methods in Molecular Biology 893
Springer-Verlag GmbH, Humana Press Inc., Juni 2012
539 S. - Sprache: Englisch - 98 schwarz-weiße und 11 farbige Abbildungen, 19 schwarz-weiße Tabellen - 261x186x35 mm Book

ISBN: 1617798843
EAN: 9781617798849

Protein modifications and changes made to them, as well as the quantities of expressed proteins, can define the various functional stages of the cell. Accordingly, perturbations can lead to various diseases and disorders. As a result, it has become paramount to be able to detect and monitor post-translational modifications and to measure the abundance of proteins within the cell with extreme sensitivity. While protein identification is an almost routine requirement nowadays, reliable techniques for quantifying unmodified proteins (including those that escape detection under standard conditions, such as protein isoforms and membrane proteins) is not routine. Quantitative Methods in Proteomics gives a detailed survey of topics and methods on the principles underlying modern protein analysis, from statistical issues when planning proteomics experiments, to gel-based and mass spectrometry-based applications. The quantification of post-translational modifications is also addressed, followed by the "hot" topics of software and data analysis, as well as various overview chapters which provide a comprehensive overview of existing methods in quantitative proteomics. Written in the successful Methods in Molecular Biology(TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls.   Authoritative and easily accessible, Quantitative Methods in Proteomics serves as a comprehensive and competent overview of the important and still growing field of quantitative proteomics.

Borovansky, Jan (Herausgeber); Riley, Patrick A. (Herausgeber)
Melanins and Melanosomes Biosynthesis, Biogenesis, Physiological, and Pathological Functions
Wiley VCH Verlag GmbH, Wiley-VCH, Juni 2011
407 S. - Sprache: Englisch - 200 schwarz-weiße und 18 farbige Abbildungen, 100 schwarz-weiße Tabellen - 245x176x28 mm

ISBN: 3527328920
EAN: 9783527328925

The surface pigmentation of vertebrates is controlled by specialized cells able to synthesize a variety of pigments collectively known as melanins. Recent research has shown that melanins are produced not only in the skin but also in many other sites such as the eye, inner ear, muscles, etc., - where they are engaged in some unanticipated roles. The details of the synthetic pathway, the complexities of its regulation and biological significance that have been unravelled in recent research comprise a fascinating story and are of key importance in understanding the nature of diseases, including malignant melanoma one of the most rapidly spreading cancers.

Buzzini, Pietro (Herausgeber); Margesin, Rosa (Herausgeber)
Cold-adapted Yeasts Biodiversity, Adaptation Strategies and Biotechnological Significance
Springer, Springer Berlin, Oktober 2013
2014. - 564 S. - Sprache: Englisch - 244x161x38 mm Book

ISBN: 3642396801
EAN: 9783642396809

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.

Baici, Antonio
Kinetics of Enzyme-Modifier Interactions Theory and Diagnosis of Inhibition and Activation Mechanisms
Springer-Verlag KG, Springer Wien, Juli 2015
489 S. - Sprache: Englisch - 242x172x28 mm

ISBN: 3709114012
EAN: 9783709114018

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.
