Proteins fixing

NAD+ and NADP+. This difference reflects the chemical difference between the vitamins riboflavin and nicotinamide which form the oxidation-reduction centers of the coenzymes. Another difference is that NAD+ and NADP+ tend to be present in free forms within cells, diffusing from a site on one enzyme to a site on another. These coenzymes are sometimes tightly bound but flavin coenzymes are usually firmly bound to proteins, fixed, and unable to move. Thus, they... 

The procedure used for the gels shown in Fig. 4.2 was that of Swank and Munkres (ref. 328), except the samples were run for 18 hr at a constant current of 1.5 mA/gel and the protein-fixing solution used after electrophoresis contained 4 5 1 methanol-water-trichloroacetic acid. 

Unlike most carbohydrate and lipid, protein contains nitrogen required for incorporation into a wide range of compounds (Table 22-4). Although the synthesis of proteins fixes nitrogen into those proteins, they are synthesized in direct response to specific needs. Dietary protein nitrogen is used for the synthesis of nitrogen-containing compounds in response to specific hormones suchas insulin.

The protein orientational averj ing in Eqs. (3), (5), (6), and (8) requires a transformation between laboratory-fixed and protein-fixed coordinates. The protein-fixed axes (abc) can be reoriented into the laboratory-fixed axes (jcyz) by applying a sequence of counterclockwise rotations through the independent Euler angles The first rotation is made through... 

If fluorescence arising from a particular transition m -> 0 is monitored after exciting a particular absorption band 0 - , the protein-fixed absorption and emission transition moment directions can be specified without loss of generality as /i = (001), v = (abc). In this case, Eq. (9) yields... 

Equation (29) indicates that since the protein-fixed moment direction and the order parameter both influence the linear dichroism, the latter technique alone cannot determine the projection cos of the moment along the protein symmetry axis unless (P2) is independently known. Even when (P2) is given, linear dichroism studies give no information about the azimuthal moment orientation of the chromophore in the protein frame ... 

The samples A2-MNP-0, A2-MNP-1, Tl-MNP-0, Tl-MNP-1 were centrifugated at 120,000 g during 1 h on Beckman Coulter (Austria). On these conditions MNPs precipitate, but macromolecules physically adsorbed on MNPs remain in supernatant liquid. The precipitates containing MNPs and protein fixed on MNPs surface were dissolved in... 

MjF is the protein fixed frame where the diffusion tensor of the protein, is diagonal. 

VF is the protein fixed frame having the z axis aligned with the director of the orienting potential. 

White, or yellow, mustard (5. alba) contains the glucosinolate sinalbin, which on hydrolysis by enzymes present (myrosin or glucosinolases) yields /i-hydroxybenzyl isothiocyanate (a relatively nonvolatile compound), -hydroxybenzylamine, and other similar components (proteins, fixed oils, sinapine, rhamnogalacturonan mucilage, etc.) as brown mustard (jiangsu marsh).
