Membrane Protein Structure Determination
Membrane proteins, representing nearly 40% of all proteins, are key components of cells involved in many cellular processes, yet only a small number of their structures have been determined. Membrane Protein Structure Determination: Methods and Protocols presents many detailed techniques for membrane protein structure determination used today by bringing together contributions from top experts in the field. Divided into five convenient sections, the book covers various strategies to purify membrane proteins, approaches to get three dimensional crystals and solve the structure by x-ray diffraction, possibilities to gain structural information for a membrane protein using electron microscopy o...
Membrane Protein Structure and Function Characterization
In this present volume, different approaches are detailed to produce membrane proteins, purify them, study their function, determine their structure, and model them in membrane. Since every membrane protein behaves mostly in a unique way /fashion, knowledge of guidelines and tricks may help to increase chances to express, purify and characterize a peculiar membrane protein. Production of correctly folded protein remains a challenge. Moreover, getting a functional and stable protein requires to optimize membrane mimicking environments that can be detergent or artificial membranes. In some cases, the finding of the correct ligand which will stabilize the desired conformation is needed. In othe...
Enzyme Catalysis and Control
Current Topics in Cellular Regulation: Volume 24, Enzyme Catalysis and Control is a compendium of papers that discusses phosphoryl transfer reactions, the role of water on the free energy of hydrolysis of pyrophosphate, and the hormonal actions of vitamin D. Other papers describe the regulation lipid metabolism by a lipid-carrying protein, the GABA, and taurine enzymes in mammalian brain. One paper examines the role of vitamin D in the metabolism of cells, as well as in the whole animal. Upon absorption in the body, the vitamin undergoes various metabolic transformations before interacting with specific receptors, and then inducting the genome in the target tissues to generate biological and...
Membrane Proteins Production for Structural Analysis
This book updates the latest development in production, stabilization and structural analysis techniques of membrane proteins. This field has made significant advances since the elucidation of the first 3-D structure of a recombinant G Protein Coupled Receptor (GPCR), rhodopsin, with the structure of several more GPCRs having been solved in the past five years. In fact, the 2012 Nobel Prize in Chemistry was awarded for groundbreaking discoveries on the inner workings of GPCRs. This book is essential reading for all researchers, biochemists and crystallographers working with membrane proteins, who are interested by the structural characterization of their favorite protein and who wish to follow the expression, migration, modifications and recycling of a membrane protein.
The Sodium Pump
The sodium of animal cell membranes converts the chemical energy obtained from the hydrolysis of adenosine 5' -triphosphate into a movement of the cations Na + and K + against an electrochemical gradient. The gradient is used subse quently as an energy source to drive the uptake of metabolic substrates in polar epithelial cells and to use it for purposes of communications in excitable cells. The biological importance of the sodium pump is evident from the fact that be tween 20-70% of the cell's metabolic energy is consumed for the pumping pro cess. Moreover, the sodium pump is an important biological system involved in regulatory processes like the maintenance of the cells' and organism's wa...
Current Topics in Cellular Regulation
Current Topics in Cellular Regulation: Volume 25 is a collection of papers that deals with GTP, the central regulator of cellular anabolism, and the quantitative approach to metabolic control. , Other papers describe the inactivation and aldolases by limited proteolysis by lysosomal cathepsin M, the regulatory functions of proline, pyrroline-5-carboxylic acid, as well as the characteristics of a hormonal regulation of amino acid transport. One paper suggests that GTP, possibly acting through high guanine nucleotide energy charge, acts to stimulate a wide variety of anabolic processes involved in cell growth or proliferation. Another paper proposes that lysosomes are responsible for the degra...

Structure and Function of Sarcoplasmic Reticulum
Structure and Function of Sarcoplasmic Reticulum is a compendium of papers from an International Conference on Sarcoplasmic Reticulum held in Japan on November 1-4, 1982. Section I is a review of sarcoplasmic reticulum including the "discovery" of the relaxing factor, the calcium binding of relaxing factor, as well as phosphate transfer and calcium transport coupling. Section II involves the chemistry and structure of the calcium pump protein in sarcoplasmic reticulum. One paper describes the role of protein-lipid interactions in the organization and function of biomembranes. Section III considers the kinetics and thermodynamics of the calcium pumping mechanism, particularly the binding of l...

Modulation by Molecular Interactions
Current Topics in Cellular Regulation, Volume 26: Modulation by Molecular Interactions covers various aspects of biochemical regulation that were presented in the International Symposium on the Molecular Basis of Cellular Regulation held at the National Institutes of Health on May 3-5, 1984. The book discusses the coordination and control of cellular metabolism and function, focusing on modulation by molecular interactions. Biochemists, molecular biologists, geneticists, microbiologists, and physiologists will find the book invaluable.
