Functional properties

Enzymes are proteins that catalyze chemical reactions. A protein is simply a polypeptide composed of amino acids linked by a peptide bond, and the term generally, but not always, refers to the folded conformation. To understand how an enzyme functions, including its binding and functional properties, it is necessary to know the properties of the amino acids and how the amino acids are linked together, including the torsion angles of the bonds and the space occupied, and the interactions of the atoms leading to the final conformations of the folded protein.

From this Chapter we will study thermal properties of matter, that is what means the terms “hot” or “cold”, what is the difference between “heat” and “temparature”, and the laws relative to these concepts. We will know that the thermal phenomena are determined by internal motions of molecules inside a matter. There exists a form of energy which is called thermal energy, or “heat”, which is the total energy of all molecular motions, or internal energy.

The Nobel Prize in Medicine 1968 for interpretation of the genetic code and its function in protein synthesis and in Chemistry 2009 for studies of the structure and function of the ribosome highlighted the ground-breaking experiment performed on May 15, 1961 by Nirenberg and Matthaei and their principal breakthrough on the creation of "cell-free protein synthesis (CFPS) system". Since then the continuous technical advances have revitalized CFPS system as a simple and powerful technology platform for industrial and high-throughput protein production....

Let X be a projective manifold and f : X → X a rational mapping with large topological degree, dt λk−1 (f ) := the (k − 1)th dynamical degree of f . We give an elementary construction of a probability measure µf such that d−n (f n )∗ Θ → µf for every smooth probability measure Θ on X. We show t that every quasiplurisubharmonic function is µf -integrable. In particular µf does not charge either points of indeterminacy or pluripolar sets, hence µf is f -invariant with constant jacobian f ∗ µf = dt µf...

The use of private property rights to regulate natural resources is a con- troversial topic because it touches upon two critical issues: the allocation of wealth in society and the conservation and management of limited resources. This book explores the extension of private property rights and market mechanisms to natural resources in international areas from a legal perspective. It uses marine fisheries to illustrate the issues that can arise in the design of regulatory regimes for natural resources. ...

There have been major breakthroughs in lung surfactant (LS) research over the last two decades that have changed our concept of how and why the material works well at the lung air–water interface. From the initial ideas of a surface active material lining the alveoli to the seminal concepts of how low surface tension is reached, the classical ideas about Comroe’s “extraordinary juice” requires revision and re-thinking.

The multidrug resistance-associated protein transporter ABCC1 (MRP1) is an integral plasma membrane protein involved in the multidrug resistance phenotype. It actively expels a number of cytotoxic molecules from cells. To gain insight into the modulation of the functional properties of this integral membrane protein by cholesterol, a main component of the lipid bilayer, we used multidrug-resistant GLC4⁄ADR cells,

We propose a two-step inversion of three-component seismograms that ( 1) recovers the far-field source time function at each station and (2) estimates the distribution of co-seismic slip on the fault plane for small earthquakes (magnitude 3 to 4). The empirical Green’s function (EGF) method consists of finding a small earthquake located near the one we wish to study and then performing a deconvolution to remove the path, site, and instrumental effects from the main-event signal.

This is the second book containing examples from the Theory of Complex Functions. The first topic will be examples of the necessary general topological concepts. Then follow some examples of complex functions, complex limits and complex line integrals. Finally, we reach the subject itself, namely the analytic functions in general. The more specific properties of these analytic functions will be given in the books to follow.

Insect development is driven by the action of ecdysteroids on morphogenetic processes. The classic ecdysteroid receptor is a protein heterodimer com-posed of two nuclear receptors, the ecdysone receptor (EcR) and Ultraspira-cle (USP), the insect ortholog of retinoid X receptor. The functional properties of EcR and USP vary among insect species, and provide a basis for identifying novel and species-specific insecticidal candidates that disrupt this receptor’s normal activity.
