Organized into eight chapters, this volume begins with an overview of the occurrence of the enzyme in plants and microorganisms. This text then examines the biosynthesis of aromatic amino acids and vitamins, which is proving an interesting model system for the study of regulation. Other chapters consider the control of cholesterol biosynthesis in normal tissues, with emphasis on the pathologic implications of derangements of cholesterol feedback control. This book discusses as well the aspects of the biogenesis of yeast mitochondria. The final chapter deals with regulation in the pyrimidine biosynthetic pathway at the level of enzyme activity.

The book contains 34 chapters covering techniques for detection, isolation, and purification of antibodies (including dansylation, two-dimensional chromatography, isoelectric focusing, polyacrylamide gel electrophoresis, and isotachophoresis); measurement of equilibrium constants (equilibrium dialysis, filtration, and sedimentation); and isotope and fluorescent labeling and detection of cell-surface components. Techniques such as isotope laboratory maintenance; chemical modification of proteins, haptens, and solid supports, and haptenation of viable biological carriers; production of antisera against allotypes and histocompatibility antigens and production of antibody with clonai dominance; histocompatibility and MLR testing; and cell separation by haptenated gels and by velocity sedimentation of rosette-forming cells are also discussed. Other chapters cover detection of antibody-secreting and alloantigen-binding cells; immune responses in vitro and their analysis by limiting dilution; production of T-cell factors; hybridoma production by cell fusion; maintenance of cell lines and cloning in semisolid media; and the mathematical analysis of immunological data.

    • Boris F. Poglazov
    • English
    Structure and Functions of Contractile Proteins focuses on the analysis of problems on the structure and functions of contractile proteins in which substantial progress has been achieved. The book first offers information on the protein constitution of myofibrils and myosin, including adenosinetriphosphat... activity, reaction with actin, and myosin molecule. The text also ponders on the polymerization of actin, tropomyosin, and the theory of contraction. Discussions focus on model experiments and molecular basis of contraction; structural interrelations of muscle proteins; features of the process of polymerization of actin; and size of the actin molecule. The text elaborates on the contractile proteins of the elementary motor structures of cells, as well as the chemical composition and physicochemical and enzymic properties of flagella and cilia; achromatin apparatus and movement of chromosomes; and structure of the flagella and cilia. Motor apparatus of bacteriophage and features of the movement of protoplasm and the mechanism of permeability are also discussed. The manuscript is a reliable source of data for readers interested in the structure and functions of contractile proteins.

  • Inequalities

    Theory of Majorization and Its Applications
    • 1st Edition
    • Volume 143
    • Ingram Olkin + 1 more
    • English
    Although they play a fundamental role in nearly all branches of mathematics, inequalities are usually obtained by ad hoc methods rather than as consequences of some underlying "theory of inequalities." For certain kinds of inequalities, the notion of majorization leads to such a theory that is sometimes extremely useful and powerful for deriving inequalities. Moreover, the derivation of an inequality by methods of majorization is often very helpful both for providing a deeper understanding and for suggesting natural generalizations.Anyo... wishing to employ majorization as a tool in applications can make use of the theorems; for the most part, their statements are easily understood.
