Alternative structural state of transferrin. The crystallographic analysis of iron-loaded but domain-opened ovotransferrin N-lobe. (1/154)

Transferrins bind Fe3+ very tightly in a closed interdomain cleft by the coordination of four protein ligands (Asp60, Tyr92, Tyr191, and His250 in ovotransferrin N-lobe) and of a synergistic anion, physiologically bidentate CO32-. Upon Fe3+ uptake, transferrins undergo a large scale conformational transition: the apo structure with an opening of the interdomain cleft is transformed into the closed holo structure, implying initial Fe3+ binding in the open form. To solve the Fe3+-loaded, domain-opened structure, an ovotransferrin N-lobe crystal that had been grown as the apo form was soaked with Fe3+-nitrilotriacetate, and its structure was solved at 2.1 A resolution. The Fe3+-soaked form showed almost exactly the same overall open structure as the iron-free apo form. The electron density map unequivocally proved the presence of an iron atom with the coordination by the two protein ligands of Tyr92-OH and Tyr191-OH. Other Fe3+ coordination sites are occupied by a nitrilotriacetate anion, which is stabilized through the hydrogen bonds with the peptide NH groups of Ser122, Ala123, and Gly124 and a side chain group of Thr117. There is, however, no clear interaction between the nitrilotriacetate anion and the synergistic anion binding site, Arg121.  (+info)

Bruton's tyrosine kinase deficiency in macrophages inhibits nitric oxide generation leading to enhancement of IL-12 induction. (2/154)

We show that macrophages of X-linked immunodeficient mice with a mutant nonfunctional Bruton's tyrosine kinase produce less NO than wild-type macrophages in response to a variety of stimuli. Induction of the inducible NO synthase (iNOS) protein, the transcription factor IFN regulatory factor-1 involved in iNOS expression, and the transcription factor STAT-1 involved in regulating IFN regulatory factor-1 induction are all poorer in X-linked immunodeficient than in wild-type macrophages. On the other hand, induction of IL-12 is higher in X-linked immunodeficient than in wild-type macrophages. Macrophage IL-12 induction is enhanced by iNOS inhibitors such as aminoguanidine and thiocitrulline and is inhibited by NO generation via sodium nitroprusside. There is relative enhancement of IFN-gamma production by immune T cells from mice immunized under aminoguanidine cover. Our data thus suggest that Bruton's tyrosine kinase participates in signaling for iNOS induction via IFN regulatory factor-1 in macrophages and that NO is an inhibitor of IL-12 induction.  (+info)

Crystal structure of hen apo-ovotransferrin. Both lobes adopt an open conformation upon loss of iron. (4/154)

The three-dimensional crystal structure of hen apo-ovotransferrin has been solved by molecular replacement and refined by simulated annealing and restrained least squares to a 3.0-A resolution. The final model, which comprises 5312 protein atoms (residues 1 to 686) and 28 carbohydrate atoms (from two monosaccharides attached to Asn(473)), gives an R-factor of 0.231 for the 11,989 observed reflections between 20.0- and 3.0-A resolution. In the structure, both empty iron binding clefts are in the open conformation, lending weight to the theory that Fe(3+) binding or release in transferrin proceeds via a mechanism that involves domain opening and closure. Upon opening, the domains rotate essentially as rigid bodies. The two domains of the N-lobe rotate away from one another by 53 degrees, whereas the C-lobe domains rotate away each another by 35 degrees. These rotations take place about an axis that passes through the two beta-strands, linking the domains. The domains of each lobe make different contacts with one another in the open and closed forms. These contacts form two interdomain interfaces on either side of the rotation axis, and domain opening or closing produces a see-saw motion between these two alternative close-packed interfaces. The interdomain disulfide bridge (Cys(478)-Cys(671)), found only in the C-lobe, may restrict domain opening but does not completely prevent it.  (+info)

The crystal structure of a T cell receptor in complex with peptide and MHC class II. (5/154)

The crystal structure of a complex involving the D10 T cell receptor (TCR), 16-residue foreign peptide antigen, and the I-Ak self major histocompatibility complex (MHC) class II molecule is reported at 3.2 angstrom resolution. The D10 TCR is oriented in an orthogonal mode relative to its peptide-MHC (pMHC) ligand, necessitated by the amino-terminal extension of peptide residues projecting from the MHC class II antigen-binding groove as part of a mini beta sheet. Consequently, the disposition of D10 complementarity-determining region loops is altered relative to that of most pMHCI-specific TCRs; the latter TCRs assume a diagonal orientation, although with substantial variability. Peptide recognition, which involves P-1 to P8 residues, is dominated by the Valpha domain, which also binds to the class II MHC beta1 helix. That docking is limited to one segment of MHC-bound peptide offers an explanation for epitope recognition and altered peptide ligand effects, suggests a structural basis for alloreactivity, and illustrates how bacterial superantigens can span the TCR-pMHCII surface.  (+info)

Vascular endothelial growth factor (VEGF) in cartilage neovascularization and chondrocyte differentiation: auto-paracrine role during endochondral bone formation. (6/154)

Vascular endothelial growth factor/vascular permeability factor (VEGF/VPF) induces endothelial cell migration and proliferation in culture and is strongly angiogenic in vivo. VEGF synthesis has been shown to occur in both normal and transformed cells. The receptors for the factor have been shown to be localized mainly in endothelial cells, however, the presence of VEGF synthesis and the VEGF receptor in cells other than endothelial cells has been demonstrated. Neoangiogenesis in cartilage growth plate plays a fundamental role in endochondral ossification. We have shown that, in an avian in vitro system for chondrocyte differentiation, VEGF was produced and localized in cell clusters totally resembling in vivo cartilage. The factor was synthesized by hypertrophic chondrocytes and was released into their conditioned medium, which is highly chemotactic for endothelial cells. Antibodies against VEGF inhibited endothelial cell migration induced by chondrocyte conditioned media. Similarly, endothelial cell migration was inhibited also by antibodies directed against the VEGF receptor 2/Flk1 (VEGFR2). In avian and mammalian embryo long bones, immediately before vascular invasion, VEGF was distinctly localized in growth plate hypertrophic chondrocytes. In contrast, VEGF was not observed in quiescent and proliferating chondrocytes earlier in development. VEGF receptor 2 colocalized with the factor both in hypertrophic cartilage in vivo and hypertrophic cartilage engineered in vitro, suggesting an autocrine loop in chondrocytes at the time of their maturation to hypertrophic cells and of cartilage erosion. Regardless of cell exposure to exogenous VEGF, VEGFR-2 phosphorylation was recognized in cultured hypertrophic chondrocytes, supporting the idea of an autocrine functional activation of signal transduction in this non-endothelial cell type as a consequence of the endogenous VEGF production. In summary we propose that VEGF is actively responsible for hypertrophic cartilage neovascularization through a paracrine release by chondrocytes, with invading endothelial cells as a target. Furthermore, VEGF receptor localization and signal transduction in chondrocytes strongly support the hypothesis of a VEGF autocrine activity also in morphogenesis and differentiation of a mesoderm derived cell.  (+info)

Effect of conalbumin on the activity of Syn 2190, a 1,5 dihydroxy-4-pyridon monobactam inhibitor of AmpC beta-lactamases. (7/154)

Syn 2190, a 1,5 dihydroxy-4-pyridon monobactam inhibitor of AmpC enzymes, was tested against beta-lactamase-producing bacteria with piperacillin, piperacillin-tazobactam and ceftazidime as partner drugs. In the presence of conalbumin as an iron chelator, Syn 2190 potentiated these drugs against most AmpC producers, although Klebsiella spp. with plasmidic AmpC enzymes were an exception. Potentiation was much weaker without conalbumin, suggesting that Syn 2190 exploits a ferric uptake pathway, as do catecholic cephalosporins. Syn 2190 had little ability to potentiate partner drugs against strains with other beta-lactamase types but, with conalbumin, increased the activity of piperacillin-tazobactam against Escherichia coli transconjugants producing various class A or D enzymes.  (+info)

Proteins with similar architecture exhibit similar large-scale dynamic behavior. (8/154)

We have investigated the similarities and differences in the computed dynamic fluctuations exhibited by six members of a protein fold family with a coarse-grained Gaussian network model. Specifically, we consider the cofactor binding fragment of CysB; the lysine/arginine/ornithine-binding protein (LAO); the enzyme porphobilinogen deaminase (PBGD); the ribose-binding protein (RBP); the N-terminal lobe of ovotransferrin in apo-form (apo-OVOT); and the leucine/isoleucine/valine-binding protein (LIVBP). All have domains that resemble a Rossmann fold, but there are also some significant differences. Results indicate that similar global dynamic behavior is preserved for the members of a fold family, and that differences usually occur in regions only where specific function is localized. The present work is a computational demonstration that the scaffold of a protein fold may be utilized for diverse purposes. LAO requires a bound ligand before it conforms to the large-scale fluctuation behavior of the three other members of the family, CysB, PBGD, and RBP, all of which contain a substrate (cofactor) at the active site cleft. The dynamics of the ligand-free enzymes LIVBP and apo-OVOT, on the other hand, concur with that of unliganded LAO. The present results suggest that it is possible to construct structure alignments based on dynamic fluctuation behavior.  (+info)

Ovotransferrin (conalbumin) is a glycoprotein of egg white albumen. Egg white albumen is composed of multiple proteins and ovotransferrin is the most heat reliable protein of them all. It has a molecular weight of 76,000 daltons and contains about 700 amino acids. Ovotransferrin makes up approximately 13% of egg albumen (in contrast to ovalbumin, which comprises 54%). As a member of the transferrin and metalloproteinase family, ovotransferrin has been found to produce heat shock proteins. When these heat shock proteins are induced in the skin, they provide protection against cold stress and other environmental stresses. Ovotransferrin is folded in a way that forms two lobes (N- and C- terminals) and each lobe consists of a binding site. Each lobe is then divided into two domains of 160 amino acid residues. Its structure also consists of fifteen disulfide crosslinks and no free sulfhydryl groups. Disulfide groups stabilize the tertiary structures of proteins. Transferrins, are iron binding ...
Ovotransferrin, a member of the transferrin family, is the second main protein found in egg white. Ovotransferrin was reported to have antimicrobial, antioxidant, and immunomodulating activities. The aim of this work was to characterize the cellular and molecular functions of egg white ovotransferrin on osteoclasts differentiation and function. Osteoclasts were prepared from mouse macrophage RAW 264.7 cells stimulated with receptor activator of nuclear factor κB ligand (RANKL). Ovotransferrin inhibited osteoclasts differentiation and the calcium–phosphate resorptive ability via the suppression of RANKL-induced nuclear factor κ-light chain-enhancer of activated B cells (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. Ovotransferrin induced apoptosis of matured osteoclasts, accompanied by increased expression of Bcl-2-like protein 11 (Bim) and Bcl-2-assoicated death promoter (Bad), but decreased expression of B-cell lymphoma 2 (Bcl-2) and B-cell lymphoma

A copper bowl assists in creating a tighter bond in reactive sulfur items such as egg whites. The bond created is so tight that the sulfurs are prevented from reacting with any other material. Copper bowls produce a yellowish, creamy foam that is harder to overbeat than the foam produced using glass or stainless steel bowls. When you whisk egg whites in a copper bowl, some copper ions migrate from the bowl into the egg whites. The copper ions form a yellow complex with one of the proteins in eggs, conalbumin. The conalbumin-copper complex is more stable than the conalbumin alone, so egg whites whipped in a copper bowl are less likely to denature (unfold ...

Ovalbumin is the most abundant protein in albumen. Classed as phosphoglycoprotein, during storage, it converts into s-ovalbumin (5% at the time of laying) and can reach up to 80% after six months of cold storage. Ovalbumin in solution is heat-resistant. Denaturation temperature is around 84°C, but it can be easily denatured by physical stresses. Conalbumin/ovotransferrin is a glycoprotein which has the capacity to bind the bi- and trivalent metal cations into a complex and is more heat sensitive than ovalbumin. At its isoelectric pH (6.5), it can bind two cations and assume a red or yellow color. These metal complexes are more heat stable than the native state. Ovomucoid is the major allergen from egg white and is a heat-resistant glycoprotein found to be a trypsin inhibitor. Lysozyme is a holoprotein which can lyse the wall of certain Gram-positive bacteria and is found at high levels in the chalaziferous layer and the chalazae which anchor the yolk towards the middle of the egg. Ovomucin is a ...

1. According to the Fletcher-Huehns hypothesis there exists a functional difference between the two iron-binding sites of transferrin.. 2. The aim of the study presented was to evaluate this hypothesis in a homogeneous system, with human bone marrow cells and pure human monoferric transferrins A and B.. 3. For this reason normal human bone marrow cells were incubated with human monoferric transferrin. The monoferric transferrins A and B were obtained by selective labelling at different pH of apotransferrin followed by preparative isoelectric focusing in granulated gels. The uptake of iron by the cell suspensions from monoferric transferrins A and B was equal.. 4. In a heterogeneous but more active system for the removal of iron from human transferrin in vitro the two human monoferric transferrins did not show any significant functional differences.. 5. No support for the Fletcher-Huehns hypothesis could be obtained. ...

α-Crystallin, a member of small heat shock protein (sHsp) family, is comprised of αA and αB subunits and acts as a molecular chaperone by interacting with unfolding proteins to prevent their aggregation. The αA-crystallin homopolymer consists of 30-40 subunits that are undergoing dynamic exchange. α-Crystallin and αA-crystallin are poorer chaperones in the presence of the crowding agent, dextran. Using fluorescence resonance energy transfer, it is shown that the αAcrystallin subunit exchange rate strongly increased with temperature. Binding of reduced ovotransferrin to αA-crystallin markedly decreases the rate of subunit exchange, as does the presence of dextran. In addition, in the presence of dextran the effect of reduced ovotransferrin on decreasing the rate of subunit exchange of αA-crystallin is stronger than in the absence of dextran. Under the conditions of molecular crowding, the αA-crystallin subunit exchange rate is not temperature-dependent. The exchange rate of αA-crystallin
An increased plasma transferrin level is often seen in patients suffering from iron deficiency anemia, during pregnancy, and with the use of oral contraceptives, reflecting an increase in transferrin protein expression. When plasma transferrin levels rise, there is a reciprocal decrease in percent transferrin iron saturation, and a corresponding increase in total iron binding capacity in iron deficient states[14] A decreased plasma transferrin can occur in iron overload diseases and protein malnutrition. An absence of transferrin results from a rare genetic disorder known as atransferrinemia, a condition characterized by anemia and hemosiderosis in the heart and liver that leads to heart failure and many other complications. Transferrin and its receptor have been shown to diminish tumour cells when the receptor is used to attract antibodies.[9] ...
Total Iron Binding Capacity (TIBC): Measures all of the proteins in the blood that are available to bind with iron, including transferrin. Since transferrin is the primary iron-binding protein, the TIBC test is a good indirect measurement of transferrin. The body produces transferrin in relationship to the need for iron. When iron stores are low, transferrin levels increase and vice versa. In healthy people, about one-third of the binding sites on transferrin are used to transport iron ...

Effect of Electromagnetic Mobile Radiation on Chick Embryo Development Fatma Al-Qudsi and Solafa Azzouz Biology Department, Science Faculty, King Abdulaziz University, Jeddah, Saudi Arabia P.O. Box 42650, Jeddah 21551, Saudi Arabia [email protected] Abstract: The widespread use of mobile phones in the last decade has increased the concern about its potential effects on human body. This research aims to study the effect of electromagnetic waves emitted from mobile phones on chick embryos development. Fertile hen eggs were divided into two groups control and treated group. Both groups were incubated at 37.5 ◦C. The treated group had an active mobile device (900MHz- 1800MHz) during incubation. The mobile was rung 4 times daily for 15 minutes each time. Embryos were extracted on days 7, 10, and 14 of incubation. Congenital malformations were seen in treated embryos (bigger embryos, subcutaneous bleeding, and brain malformation) compared to the controls. Also increased eye growth in 7 and 10 ...

4. You said you thought egg protein is probably better for you. No, egg protein isnt necessarily better for you. Why not just eat eggs???? I just called 3 distributors of egg white protein powders, only one of whom could even vaguely describe how the protein powder was made. [What I gathered is that] its basically separated from the yolk, pasteurized for a few minutes in 134 degree heat and then spray dried, which is drying it with more heat to make a powder. Im not saying that cooking eggs isnt a good idea, but who knows how high the heat is, for how long they heat it, and where the eggs come from in the first place. One of the 2 big egg white protein powder manufacturers is in China, although I had to find that out for myself since the guy at Jay Robbs refused to give me their manufacturers name... In my opinion, its these kinds of overly processed foods that make us have sensitivities. Ive had more people come in lately who were like, I didnt used to be sensitive to eggs (or soy), ...

Iron is an essential component of life. However, iron is also a potent biological toxin. Thus the bioavailability of iron must be stringently regulated. At the cellular level, if there is too little iron, a cell will lack the ability to meet its metabolic and biosynthetic requirements. If there is too much iron the cell become vulnerable to oxidative stress. Iron requiring metabolic reactions are found in both nuclei and cytoplasm and molecules in both compartments are vulnerable to oxidative stress. Indeed, iron-binding sites have been reported on DNA and iron induced DNA damage is well established. In the cytoplasm, ferritin regulates iron bioavailability. Recently, we and two other groups have provided evidence that ferritin is present in the nuclei of some cells. By virtue of its ability to take up and release iron, ferritin may be uniquely suited to both deliver iron to the nucleus as well as provide protection from iron induced oxidative stress. Our preliminary data show that nuclear ...
We have studied the pharmacological and toxicological effects of cardiovascular drugs on chick embryos using electrocardiograms in order to develop alternatives to the use of mammals. Recently, proarrhythmic actions induced by antiarrhythmic drugs have been widely studied. In this study, we investigated the pharmacological effects of antiarrhythmic drugs, Ia(procainamide), Ib(lidocaine), Ic(flecainide), II(propranolol) and IV(verapamil)types, as classified by Vaughan Williams. When a single injection of drugs was performed into the air sac of fertile eggs of White Leghorns on the 16th day of incubation, all drugs decreased HR in a dose-dependent manner. Also, when higher dosages of drugs were injected, these drugs induced various kinds of arrhythmias, i.e., S-A or A-V blocks, as shown in mammals. The intervals of PQ, QRS and QT waves varied depending on the drugs used. However, the ECG waves exhibited the same changes seen in mammals with a few exceptions. Our ECG recording system using chick ...
TY - JOUR. T1 - Specification and determination of limb identity. T2 - Evidence for inhibitory regulation of Tbx gene expression. AU - Saito, Daisuke. AU - Yonei-Tamura, Sayuri. AU - Kano, Kohko. AU - Ide, Hiroyuki. AU - Tamura, Koji. PY - 2002/8/20. Y1 - 2002/8/20. N2 - Limb-type-specific expression of Tbx5/Tbx4 plays a key role in drawing distinction between a forelimb and a hindlimb. Here, we show insights into specification and determination during commitment of limb-type identity, in particular that median tissues regulate Tbx expressions. By using the RT-PCR technique on chick embryos, the onset of specific Tbx5/Tbx4 expression in the wing/leg region was estimated to be stage 13. Specification of the limb-type identity is thought to occur before stage 9, since all explants from stage 9 through 14 expressed the intrinsic Tbx gene autonomously in a simple culture medium. The results of transplantation experiments revealed that axial structures medial to the lateral plate mesoderm at the ...

We previously showed that the trafficking of newly synthesized Lyn from the Golgi to the plasma membrane involves the four charged amino acid residues (Asp346, Glu353, Asp498 and Asp499) in the C-lobe of the Lyn kinase domain (Kasahara et al., 2004). We thus hypothesized that the Lyn C-lobe has a role in Lyn trafficking through a protein-protein interaction. To search for a protein that associates with the Lyn C-lobe, we constructed a glutathione-S-transferase (GST)-Lyn C-lobe fusion protein (GST-C-lobe), which encompasses amino acids 326-506 in Lyn (Fig. 1A). We found that a 70 kDa protein (p70) was pulled down with GST-C-lobe but not with GST alone from Triton-X-100-treated HeLa cell lysates (Fig. 1B). We then constructed GST-C-lobe-mt, an alanine-substitution mutant (Fig. 1A). p70 could be pulled down with GST-C-lobe-mt but to a lesser extent than seen with GST-C-lobe (Fig. 1B), suggesting that p70 preferentially associates with the intact C-lobe. Consequently, the p70 band was excised and ...

An antibody (Ab), also known as an immunoglobulin (Ig),[1] is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen, via the Fab's variable region.[2][3] Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival). Depending on the antigen, the binding may impede the biological process causing the disease or may activate macrophages to destroy the foreign substance. The ability of an antibody to ...
Normal range of human serum albumin in adults (, 3 y.o.) is 3.5 to 5 g/dL. For children less than three years of age, the normal range is broader, 2.9-5.5 g/dL.[9]. Low albumin (hypoalbuminemia) may be caused by liver disease, nephrotic syndrome, burns, protein-losing enteropathy, malabsorption, malnutrition, late pregnancy, artefact, genetic variations and malignancy.. High albumin (hyperalbuminemia) is almost always caused by dehydration. In some cases of retinol (Vitamin A) deficiency, the albumin level can be elevated to high-normal values (e.g., 4.9 g/dL). This is because retinol causes cells to swell with water (this is also the reason too much Vitamin A is toxic).[10] This swelling also likely occurs during treatment with 13-cis retinoic acid (isotretnoin), a pharmaceutical for treating severe acne, amongst other conditions. In lab experiments it has been shown that all-trans retinoic acid down regulates human albumin production[11]. ...
1. Influence Of Dietary Lactalbumin Hydrolysate On The Immune System Of Mice And Resistance To Salmonellosis Bounous G., Stevenson M.M., Kongshavn P.A. J Infect Dis. Sep; 144(3) :281. (1981). In the present study we investigated the effect of four weeks of treatment with a diet containing lactalbumin hydrolysate (LAH: Nestlé, Vevey, Switzerland) on the immune response of C3H/HeN mice. Our data indicate that it was possible to increase the level of this type of protein in the diet above the minimum requirement (12% LAH) and thus produce augmented humoral immune responsiveness and resistance to salmonellosis.

... (ORM) or alpha-1-acid glycoprotein (α1AGp,[1] AGP or AAG) is an acute phase (acute phase protein) plasma alpha-globulin glycoprotein and is modulated by two polymorphic genes. It is synthesized primarily in hepatocytes and has a normal plasma concentration between 0.6-1.2 mg/mL (1-3% plasma protein).[2] Plasma levels are affected by pregnancy, burns, certain drugs, and certain diseases, particularly HIV.[2] The only established function of ORM is to act as a carrier of basic and neutrally charged lipophilic compounds. In medicine, it is known as the primary carrier of basic (positively charged) drugs (whereas albumin carries acidic (negatively charged) and neutral drugs), steroids, and protease inhibitors.[2][3] Aging causes a small decrease in plasma albumin levels; if anything, there is a small increase in alpha-1-acid glycoprotein. The effect of these changes on drug protein binding and drug delivery, however, appear to be minimal.[4] AGP shows a complex interaction with thyroid ...
