Green Fluorescent Protein is involved in the jellyfish, Aequorea Victoria [11, 92-95] and has very efficient emission property. It is now widely used as an excellent molecular marker in various fields of molecular biology [12, 96], There are theoretical studies investigating spectroscopy [97-104], potential surface of the excited state [105-107], and protein environmental effect [35, 101, 104, 108-110]. [Pg.111]

The possible mechanistic importance of the Fe-imidazole(histidine) bond, especially in various models for hemoglobin cooperativity, has been recognized for some time. NRVS clearly provides the first experimental method for systematic studies of how the Fe-Im bond strength can be modulated in six-coordinate hemes, both by protein environmental effects as well as by the consequences of systematic ligand change. [Pg.6261]

Because of its solubility in lipids and affinity for proteins, environmental carbon disulfide is quickly absorbed in the blood and other body tissues through inhalation or cutaneous absorption. The absorbed... [Pg.98]

Spectroscopic data support location of the radical in GAO on the Y272-C228 unit. The first indication came from UV-vis, EPR, and ENDOR studies of a one-electron oxidized form of Cu-depleted (apo) GAO, which showed the formation of a thioether-modified tyrosyl radical. " " This radical was found to be quite stable, as reflected by the oxidation potential of about-1-0.4 V (vs. normal hydrogen electrode (NHE)) which is significantly less than that of other tyrosine/ tyrosyl radical couples (cf.+0.93V for free tyrosine or +1.0V for the tyrosyl residue near the diiron site in ribonucleotide reductase, vide infra). Possible origins of this unusual stability that have been considered are the thioether substituent," the nearby W290, and/or other unspecified protein environmental effects. Coordination of this radical to Cu was then proposed for the... [Pg.717]

The structural distortion effects were evaluated by comparing with the SAC-CI results without the protein environmental effects (SAC-CI/none QM region = RET) (see Table 28.1). While the results for HG and HR were very close to that for Rh, the excitation energy of HB was 0.25 eV higher than that of Rh. This difference arises from the C6-C7 dihedral angle (see Fig. 28.1) [34-36]. In our optimized structure, the C6-C7 angle of HB was 56°, whereas that of HG, HR, and Rh ranged from —46 to -38° [16, 17]. [Pg.493]

Ethanol. Accurate projections of ethanol costs are much more difficult to make than are those for methanol. Large scale ethanol production would impact upon food costs and have important environmental consequences that are rarely cost-analyzed because of the complexity. Furthermore, for corn, the most likely large-scale feedstock, ethanol costs are strongly influenced by the credit assigned to the protein by-product remaining after the starch has been removed and converted to ethanol. [Pg.423]

Chemiluminescence has been studied extensively (2) for several reasons (/) chemiexcitation relates to fundamental molecular interactions and transformations and its study provides access to basic elements of reaction mechanisms and molecular properties (2) efficient chemiluminescence can provide an emergency or portable light source (J) chemiluminescence provides means to detect and measure trace elements and pollutants for environmental control, or clinically important substances (eg, metaboHtes, specific proteins, cancer markers, hormones, DNA) and (4) classification of the hioluminescent relationship between different organisms defines their biological relationship and pattern of evolution. [Pg.262]

Milk consists of 85—89% water and 11—15% total soflds (Table 1) the latter comprises soflds-not-fat (SNF) and fat. Milk having a higher fat content also has higher SNF, with an increase of 0.4% SNF for each 1% fat increase. The principal components of SNF are protein, lactose, and minerals (ash). The fat content and other constituents of the milk vary with the animal species, and the composition of milk varies with feed, stage of lactation, health of the animal, location of withdrawal from the udder, and seasonal and environmental conditions. The nonfat soflds, fat soflds, and moisture relationships are well estabhshed and can be used as a basis for detecting adulteration with water (qv). Physical properties of milk are given in Table 2. [Pg.350]

Applications. Immunoassays are used in many different disciplines, having clinical, industrial, agricultural, and environmental appHcations. This technique has made possible rapid analysis of such varied analytes as vimses, toxins, hormones, foreign proteins, dmgs, and insecticides. [Pg.101]

Human exposure to environmental contaminants has been investigated through the analysis of adipose tissue, breast milk, blood and the monitoring of faecal and urinary excretion levels. However, while levels of persistent contaminants in human milk, for example, are extensively monitored, very little is known about foetal exposure to xenobiotics because the concentrations of persistent compounds in blood and trans-placental transmission are less well studied. Also, more information is needed in general about the behaviour of endocrine disruptive compounds (and their metabolites) in vivo, for example the way they bind to blood plasma proteins. [Pg.16]

A wide variety of animal species are subjected to the administration of drugs during their lifetime.The various animal species can encounter drugs and other dietary additives by different routes and this is dependent on the environment in which they are kept. Intensively reared animals tend to have considerable consistency in the components of their diets and thus are much less likely to encounter the range of naturally produced compounds that extensively produced animals encounter. The desire for less expensive dietary constituents and increased efficiency of use has induced feed manufacturers and producers to add enzyme supplements to diets of most farmed animals to reduce the negative effects of indigestible dietary carbohydrates, refactory proteins and unavailable minerals such as phosphorus. This use of dietary additives to improve nutrient utilization and environmental consequences of feeding animals intensively has been the subject of intense research activity in the last five years. " The... [Pg.90]
