Proteins characteristics

A measurable DNA/RNA or protein characteristic that is an indicator of normal biological process, pathogenic process and/or response to therapeutic or other inventions, used as diagnostic and prognostic indicators.

Subsequently, similar experiments were done with viral nucleic acids. The pure viral nucleic acid, when added to cells, led to the synthesis of complete virus particles the protein coat was not required. This process is called transfection. More recently, DNA has been used in cell-free extracts to program the synthesis of RNA that functions as the template for the synthesis of proteins characteristic of the DNA... 

Small amounts of proteins characteristic of cells and membranes in general can also be found in myelin. There is evidence that tubulin is an authentic myelin-related component (Fig. 4-12B, D, CNS myelin). The 48kDa myelin/oligodendrocyte-specific protein (MOSP) is a component found only in CNS myelin and oligodendroglial membranes, which appears to associate with tubulin [41].

Traditionally, milk was paid for mainly on the basis of its fat content but milk payments are now usually based on the content of fat plus protein. Specifications for many dairy products include a value for protein content. Changes in protein characteristics, e.g. insolubility as a result of heat denaturation in milk powders or the increasing solubility of cheese proteins during ripening, are industrially important features of these products. 

Following differential sedimentation, proteins may be separated into crude fractions by the addition of increasing amounts of (NH4)2S04. Specific proteins characteristically precipitate in a limited range of salt concentrations. 

The magnetic susceptibility measurements of (159) show a molecular paramagnetism in the reduced protein characteristic of a S=l/2 compound. The absence of internal magnetic effects in the high-temperature, reduced-protein spectra are explained by the Mossbauer spectra shown in Fig. 10.

Aromatic rings—for example, phenylalanine (F), tyrosine (Y), and tryptophane (W), which give proteins characteristic UV absorption at 280 nm and form effective hydrophobic bonds especially in bonding to flat molecules. 

The currently most relevant separation and purification techniques for processing biomolecules from animal cell cultures are discussed in the sections that follow. They are classified according to the protein characteristic on which the separation is based, such as solubility, molar mass, electrical charge, adsorption properties, and biological affinity for ligands.

Because the symptoms of lactose intolerance are nonspecific, lactose intolerance needs to be differentiated from other common disorders causing diarrhea and abdominal pain or discomfort. These differential diagnoses include milk protein allergy, gastroenteritis, colitis, and irritable bowel syndrome. Allergy or sensitivity to one or more of cow s milk proteins characteristically occurs in formula-fed infants, and although no age is exempt, it is rare in the older...

SlOO Proteins A mnltifnnctional family of intracellular proteins distinguished by solution in satnrated ammonium sulfate (100% saturation) and their interactions with calcinm ions. The seminal member of the family, SlOO protein, was described as a protein unique to the nervous system. See Moore, B.W., A soluble protein characteristic of the nervous system, Biochem. Biophys.

The scope of the present review will be limited to the enzyme and protein characteristics of galactosidases, and their occurrence, isolation, characterization, and properties as catalytic agents. The topic of induced enzyme-synthesis will only be touched on, and reference will be made to original and review articles on the subject. The biological role played by these enzymes will not be discussed. Throughout the article, all glycosides discussed will be understood to be pyranoid, unless otherwise noted. 

It shonld be noted that only the derivative Ji and the partial molar volume of the protein depend on the protein characteristics all the other quantities in Eq. (9) can be determined from the characteristics of the protein-free mixed solvent. Equation (9) shows that the preferential binding parameter F23 can be decomposed into the sum of two terms. One of them, depends on the protein nature, reflected in 72i and V, and the other one depends only on the properties of the protein-free mixed solvent. 

Whereas G12 and G23 depend on the protein characteristics, Gii and G13 depend only on the characteristics of the protein-free mixed solvent.
