Chaperone activity with a redox switch. (1/11250)

Hsp33, a member of a newly discovered heat shock protein family, was found to be a very potent molecular chaperone. Hsp33 is distinguished from all other known molecular chaperones by its mode of functional regulation. Its activity is redox regulated. Hsp33 is a cytoplasmically localized protein with highly reactive cysteines that respond quickly to changes in the redox environment. Oxidizing conditions like H2O2 cause disulfide bonds to form in Hsp33, a process that leads to the activation of its chaperone function. In vitro and in vivo experiments suggest that Hsp33 protects cells from oxidants, leading us to conclude that we have found a protein family that plays an important role in the bacterial defense system toward oxidative stress.  (+info)

Kinetics of oxidation of aliphatic and aromatic thiols by myeloperoxidase compounds I and II. (2/11250)

Myeloperoxidase (MPO) is the most abundant protein in neutrophils and plays a central role in microbial killing and inflammatory tissue damage. Because most of the non-steroidal anti-inflammatory drugs and other drugs contain a thiol group, it is necessary to understand how these substrates are oxidized by MPO. We have performed transient kinetic measurements to study the oxidation of 14 aliphatic and aromatic mono- and dithiols by the MPO intermediates, Compound I (k3) and Compound II (k4), using sequential mixing stopped-flow techniques. The one-electron reduction of Compound I by aromatic thiols (e.g. methimidazole, 2-mercaptopurine and 6-mercaptopurine) varied by less than a factor of seven (between 1.39 +/- 0.12 x 10(5) M(-1) s(-1) and 9.16 +/- 1.63 x 10(5) M(-1) s(-1)), whereas reduction by aliphatic thiols was demonstrated to depend on their overall net charge and hydrophobic character and not on the percentage of thiol deprotonation or redox potential. Cysteamine, cysteine methyl ester, cysteine ethyl ester and alpha-lipoic acid showed k3 values comparable to aromatic thiols, whereas a free carboxy group (e.g. cysteine, N-acetylcysteine, glutathione) diminished k3 dramatically. The one-electron reduction of Compound II was far more constrained by the nature of the substrate. Reduction by methimidazole, 2-mercaptopurine and 6-mercaptopurine showed second-order rate constants (k4) of 1.33 +/- 0.08 x 10(5) M(-1) s(-1), 5.25 +/- 0.07 x 10(5) M(-1) s(-1) and 3.03 +/- 0.07 x 10(3) M(-1) s(-1). Even at high concentrations cysteine, penicillamine and glutathione could not reduce Compound II, whereas cysteamine (4.27 +/- 0.05 x 10(3) M(-1) s(-1)), cysteine methyl ester (8.14 +/- 0.08 x 10(3) M(-1) s(-1)), cysteine ethyl ester (3.76 +/- 0.17 x 10(3) M(-1) s(-1)) and alpha-lipoic acid (4.78 +/- 0.07 x 10(4) M(-1) s(-1)) were demonstrated to reduce Compound II and thus could be expected to be oxidized by MPO without co-substrates.  (+info)

Basic homopolyamino acids, histones and protamines are potent antagonists of angiogenin binding to ribonuclease inhibitor. (3/11250)

A radio-ribonuclease inhibitor assay based on the interaction of 125I-angiogenin with ribonuclease inhibitor (RI) was used to detect pancreatic-type ribonucleases and potential modulators of their action. We show that highly basic proteins including the homopolypeptides poly-arginine, poly-lysine and poly-ornithine, core histones, spermatid-specific S1 protein and the protamines HP3 and Z3 were strong inhibitors of angiogenin binding to RI. A minimum size of poly-arginine and poly-lysine was required for efficient inhibition. The inhibition likely resulted from direct association of the basic proteins with the acidic inhibitor, as RI bound to poly-lysine and protamines while 125I-angiogenin did not. Antagonists of the angiogenin-RI interaction are potential regulators of either angiogenin-triggered angiogenesis and/or intracellular RI function, depending on their preferential target.  (+info)

Nuclear translocation of green fluorescent protein-nuclear factor kappaB with a distinct lag time in living cells. (4/11250)

A highly fluorescent mutant form of the green fluorescent protein (GFP) has been fused to the human nuclear factor kappaB (NF-kappaB) p50 and p105 (p50/IkappaB gamma), a precursor protein of NF-kappaB p50. GFP-p50 and GFP-p105 were expressed in monkey COS-7 cells and human HeLa cells. Translocation of these chimeric proteins was observed by confocal laser scanning microscopy. GFP-p50 (without IkappaB gamma) in the transfected cells resided in the nucleus. On the other hand, GFP-p105 (GFP-p50 with IkappaB gamma) localized only in the cytoplasm before stimulation and translocated to the nucleus with stimulant specificity similar to that of native NF-kappaB/IkappaB. In addition, the translocation of NF-kappaB to the nucleus had a distinct lag time (a quiescent time) in the target cells. The lag time lasted 10-20 min after stimulation with hydrogen peroxide or tumor necrosis factor alpha. It was suggested that this might be due to the existence of a limiting step where NF-kappaB is released from NF-kappaB/IkappaB by the proteasome.  (+info)

Variants of ribonuclease inhibitor that resist oxidation. (5/11250)

Human ribonuclease inhibitor (hRI) is a cytosolic protein that protects cells from the adventitious invasion of pancreatic-type ribonucleases. hRI has 32 cysteine residues. The oxidation of these cysteine residues to form disulfide bonds is a rapid, cooperative process that inactivates hRI. The most proximal cysteine residues in native hRI are two pairs that are adjacent in sequence: Cys94 and Cys95, and Cys328 and Cys329. A cystine formed from such adjacent cysteine residues would likely contain a perturbing cis peptide bond within its eight-membered ring, which would disrupt the structure of hRI and could facilitate further oxidation. We find that replacing Cys328 and Cys329 with alanine residues has little effect on the affinity of hRI for bovine pancreatic ribonuclease A (RNase A), but increases its resistance to oxidation by 10- to 15-fold. Similar effects are observed for the single variants, C328A hRI and C329A hRI, suggesting that oxidation resistance arises from the inability to form a Cys328-Cys329 disulfide bond. Replacing Cys94 and Cys95 with alanine residues increases oxidation resistance to a lesser extent, and decreases the affinity of hRI for RNase A. The C328A, C329A, and C328A/C329A variants are likely to be more useful than wild-type hRI for inhibiting pancreatic-type ribonucleases in vitro and in vivo. We conclude that replacing adjacent cysteine residues can confer oxidation resistance in a protein.  (+info)

Purification and characterization of a novel peroxidase from Geotrichum candidum dec 1 involved in decolorization of dyes. (6/11250)

A peroxidase (DyP) involved in the decolorization of dyes and produced by the fungus strain Geotrichum candidum Dec 1 was purified. DyP, a glycoprotein, is glycosylated with N-acetylglucosamine and mannose (17%) and has a molecular mass of 60 kDa and an isoelectric point (pI) of 3.8. The absorption spectrum of DyP exhibited a Soret band at 406 nm corresponding to a hemoprotein, and its Na2S2O4-reduced form revealed a peak at 556 nm that indicates the presence of a protoheme as its prosthetic group. Nine of the 21 types of dyes that were decolorized by Dec 1 cells were decolorized by DyP; in particular, anthraquinone dyes were highly decolorized. DyP also oxidized 2,6-dimethoxyphenol and guaiacol but not veratryl alcohol. The optimal temperature for DyP activity was 30 degrees C, and DyP activity was stable even after incubation at 50 degrees C for 11 h.  (+info)

Crosslinking of DNA and proteins induced by protein hydroperoxides. (7/11250)

Exposure of DNA to several proteins peroxidized by radiation-generated hydroxyl free radicals resulted in formation of crosslinks between the macromolecules, detected by retardation and broadening of DNA bands in agarose gels. This technique proved suitable for the study of crosslinking of DNA with peroxidized BSA, insulin, apotransferrin and alpha casein, but not with several other proteins, including histones. The crosslinking depended on the presence of intact hydroperoxide groups on the protein, on their number, and on the duration of the interaction with DNA. All DNA samples tested, pBR322, pGEM, lambda/HindIII and pUC18, formed crosslinks with the peroxidized BSA. Sodium chloride and formate prevented the crosslinking if present during incubation of the peroxidized protein and DNA, but had no effect once the crosslinks had formed. The gel shift of the crosslinked DNA was reversed by proteolysis, indicating that the DNA mobility change was due to attachment of protein and that the crosslinking did not induce DNA strand breaks. The metal chelators Desferal and neocuproine reduced the extent of the crosslinking, but did not prevent it. Scavengers of free radicals did not inhibit the crosslink formation. The DNA-protein complex was not disrupted by vigorous agitation, by filtration or by non-ionic detergents. These observations show that the crosslinking of DNA with proteins mediated by protein hydroperoxides is spontaneous and probably covalent, and that it may be assisted by transition metals. It is suggested that formation of such crosslinks in living organisms could account for some of the well-documented forms of biological damage induced by reactive oxygen species-induced oxidative stress.  (+info)

Bilirubin, formed by activation of heme oxygenase-2, protects neurons against oxidative stress injury. (8/11250)

Heme oxygenase (HO) catalyzes the conversion of heme to carbon monoxide, iron, and biliverdin, which is immediately reduced to bilirubin (BR). Two HO active isozymes exist: HO1, an inducible heat shock protein, and HO2, which is constitutive and highly concentrated in neurons. We demonstrate a neuroprotective role for BR formed from HO2. Neurotoxicity elicited by hydrogen peroxide in hippocampal and cortical neuronal cultures is prevented by the phorbol ester, phorbol 12-myristate 13-acetate (PMA) via stimulation of protein kinase C. We observe phosphorylation of HO2 through the protein kinase C pathway with enhancement of HO2 catalytic activity and accumulation of BR in neuronal cultures. The neuroprotective effects of PMA are prevented by the HO inhibitor tin protoporphyrin IX and in cultures from mice with deletion of HO2 gene. Moreover, BR, an antioxidant, is neuroprotective at nanomolar concentrations.  (+info)

Refining oil-contaminated soils has a great importance especially in oil producer countries such as Iran. Different methods have been provided to eliminate oil contaminations from soil. The aim of this study was to investigate the effect of Hydrogen peroxide concentration in refining oil-contaminated soils with Fenton chemical method. To do this, a calcareous soil complex sample was collected around the Tehran oil refinery and treated with 10 and 20 percent petroleum in three replications. After reaching to balance conditions, the sample was treated using0.01, 0.02,0.12,0.24,0.47 and 0.71 equivalent of Hydrogen peroxide. The results indicated that in all level of H2O2, the eliminating efficiency in 10 percent was more than 20 percent treatment. Also a significant difference between the levels of hydrogen peroxide used in the removal of oil pollution in both surface concentrations was obtained (P|0.01).
Abstract: Hydrogen peroxide production via cathodic reduction of oxygen on self-made gas diffusion electrode was studied in an undivided system. The effects of mass ratio between graphite and PTFE, cathodic potential, pH, and gas flow rate on hydrogen peroxide output were investigated. When the mass ratio between graphite and PTFE was 2:1, pH=3, Na2SO4 concentration was 0.1 mol•L−1, oxygen flow rate was 0.4 L•min−1, and cathodic potential was −0.55 V (vs SCE), hydrogen peroxide concentration could reach about 60 mg•L−1 after 2 h. It had a good hydrogen peroxide output and current efficiency. The pH values applicable to hydrogen peroxide production could be extended to a wide range in this undivided system and this novel gas diffusion electrode system is expected to be applicable in waste water treatment. Key words: Gas diffusion electrode, Cathodic potential, Oxygen reduction, Hydrogen peroxide, Current efficiency ...

PY - 1998/5/7. Y1 - 1998/5/7. N2 - The electrochemical oxidation of H2O2 at a platinum rotating disc electrode was studied at pH 7.26 for the [H2O2] range 0-70 mM, rotation rates 630-10000 rpm and anodic potential +264 to +712 mV vs Ag/AgCl using staircase potentiometry. A mechanism is proposed to account for the steady-state current as a function of rotation rate, [H2O2] and anodic potential. This mechanism involves reversible binding of H2O2 to electrochemically generated Pt(II) surface sites, reduction of the site and inhibiting competitive adsorption of H+ and O2.

However, the precise physiological functions of PLD are not yet well understood. In this study, we examined the role of PLD activity in hydrogen peroxide (H2O2)-induced apoptosis in rat pheochromocytoma (PC12) cells. Treatment of PC12 cells with H2O2 resulted in induction of apoptosis in these cells, which is accompanied by the activation of PLD. This H2O2-induced apoptosis was enhanced remarkably when phosphatidic acid production by PLD was selectively inhibited by pre-treating the PC12 cells with 1-butanol. Expression of PLD2, but not of PLD1, correlated with increased H2O2-induced PLD activity in a ...
Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid, slightly more viscous than water. The oxidizing capacity of hydrogen peroxide is so strong that it is considered a highly reactive oxygen species. Organisms also naturally produce hydrogen peroxide as a by-product of oxidative metabolism. Consequently, nearly all living things (specifically, all obligate and facultative aerobes) possess enzymes known as catalase peroxidases, which harmlessly and catalytically decompose low concentrations of hydrogen peroxide to water and oxygen. (Wikipedia) Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution, slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and has also found use as a disinfectant and as an oxidizer. Hydrogen peroxide (H2O2) is a well-documented component of living cells. It plays important roles in ...
Hydrogen peroxide is composed of two hydrogen atoms and two oxygen atoms [HO-OH]. It is an effective germicide that is essentially composed of water with an additional oxygen atom bound to it.. It is an oxidizer, meaning it can break down organic materials for the purpose of disinfection. When hydrogen peroxide reacts with organic material it breaks down into oxygen and water and leaves no byproduct.. Hydrogen peroxide can be purchased over the counter at most drug stores and the health section of grocery and department stores.. Hydrogen peroxide is completely compatible with and necessary for life. (CSTEE Opinion, 2001).. Natural sources of hydrogen peroxide are abundant in the environment (NSF Oral Risk Assessment; 2010) where hydrogen peroxide occurs naturally at low levels in the air and water, in human and plant tissues and bacteria, and in food and beverages.. Exposure to hydrogen peroxide occurs commonly in everyday life through inhaling air or direct exposure through eye or skin contact ...
Many people are aware that it is possible to induce vomiting in dogs by using hydrogen peroxide. But using hydrogen peroxide is not without potential complications, and there are alternatives.. Hydrogen peroxide works by creating enough irritation to the mouth, esophagus and stomach lining that vomiting occurs. Mild side effects to hydrogen peroxide ingestion can include continued vomiting or poor appetite. When this occurs, the patient is typically treated with antacids and stomach protectants until the gut has a chance to heal.. In rare cases, however, the side effects do not stop at mild irritation. Severe gastritis, or inflammation of the stomach, can occur, followed by ulceration and bleeding. Although very rare, pets have died from internal bleeding due to hydrogen peroxide toxicity.. Another potential but rare side effect of hydrogen peroxide ingestion is a gas emboli, an air clot in the blood vessels. Hydrogen peroxide will release oxygen when it reacts with tissue. This excess release ...

Almost anything used in large quantities can be harmful, and using large doses of hydrogen peroxide in the garden is no exception. However, when using hydrogen peroxide on plants, the solution is usually diluted, making it especially safe. Its also approved by the U.S. Environmental Protection Agency (EPA), which gives it an extra stamp of approval.. Hydrogen peroxide is also made up of the same atoms in water, but with an extra atom of oxygen. This extra oxygen (H2O2) gives the hydrogen peroxide its beneficial properties.. Therefore, the answer to the question hydrogen peroxide damages plants is definitely no if the starch is sufficiently diluted. Different concentrations of hydrogen peroxide can be purchased. The most common solution is 3%, but it can be as high as 35%. 3% can be bought in supermarkets or pharmacies. ...

Aspects of environment protection as well as related legislation support the practical promotion of the technology of chlorine free bleaching of kraft pulps (TCF-Totally Chlorine Free). Hydrogen peroxide is one of the basic reagent applied in different schemes of TCF bleaching [7,16]. The merits of hydrogen peroxide are the ease of use and high reactivity with respect to chromophoric groups of residual lignin which are responsible for coloring cellulose pulps [17,19]. However, bleaching with the peroxide (P) firstly requires preliminary treatment removing heavy metals from pulps. The metals are responsible for catalyzing the decomposition of the peroxide anion in the alkaline medium leading to the formation of hydroxyl radicals. This in turn, results in the decrease of cellulose polymerization degree as well as the strength properties of pulps [10]. Two methods are known for the removal of metals from cellulose pulps: chelation (Q) and acid treatment at pH of 1.5 - 3 (A) [11]. Chelation ...
The inositolphosphosphingolipid phospholipase C (Isc1p) of Saccharomyces cerevisiae belongs to the family of neutral sphingomyelinases that generates the bioactive sphingolipid ceramide. In this work the role of Isc1p in oxidative stress resistance and chronological lifespan was investigated. Loss of Isc1p resulted in a higher sensitivity to hydrogen peroxide that was associated with an increase in oxidative stress markers, namely intracellular oxidation, protein carbonylation, and lipid peroxidation. Microarray analysis showed that Isc1p deficiency up-regulated the iron regulon leading to increased levels of iron, which is known to catalyze the production of the highly reactive hydroxyl radicals via the Fenton reaction. In agreement, iron chelation suppressed hydrogen peroxide sensitivity of isc1Delta mutants. Cells lacking Isc1p also displayed a shortened chronological lifespan associated with oxidative stress markers and aging of parental cells was correlated with a decrease in Isc1p activity. The
Hydrogen peroxide is a chemical compound with the formula of H2O2. Its commonly been used for medical care, to sterilize and disinfectant wounds, abrasions, and skin infections. Its naturally colourless, but the form that is sold in stores is mixed with water, so its safer, as pure hydrogen peroxide can burn the skin. It has a slight smell that isnt too unpleasant. The bottled solution you buy in stores is usually around 3%, which is suitable for your anti-insect purposes.. Hydrogen peroxide is safe to come into contact with human or pet skin, so should any of the hydrogen peroxide gnat killer come into contact, little harm will be done. Most animals will steer clear of the smell.. Hydrogen peroxide is a natural oxidizer, bleaching agent, and a disinfectant. Its effective on fungus gnats because they have a delicate body.

Regarded as a legendary healing compound, scientific evidence shows that hydrogen peroxide mouthwash and bleaching is actually harmful for teeth and may cause tissue irritation and teeth sensitivity and compromise long-term dental health. Hydrogen peroxide is praised for its antiseptic and healing properties. In fact, there is a new urban myth proclaiming that hydrogen peroxide is universally beneficial for all the body organs and tissues. Regarding dental health, this couldnt be further from the truth as evidence shows that hydrogen peroxide is actually toxic for the cells in the inner part of the teeth, also known as the dental pulp. Without a doubt, hydrogen peroxide does a really good job at bleaching and disinfecting teeth; hydrogen peroxide- based bleaching gels are essential for dentists and there is solid evidence demonstrating the efficacy of these protocols.

Hydrogen peroxide inhibits tooth decay by inhibiting plaque formation on teeth that usually forms a protective coating on disease-causing bacterial microorganisms that break down the protective layers of teeth.. However, if very strong concentrations of hydrogen peroxide are used for longer periods of time in the mouth, some side effects are likely to develop and these include;. •Increased tooth sensitivity. Concentrated hydrogen peroxide destroys the tooth enamel and dentin tissue covering up the pulp. Pulp damage will lead to exposure of blood vessels and nerves leading to increased tooth sensitivity that can be very uncomfortable.. •Tissue irritation.The acidity associated with hydrogen peroxide increases as the concentration hydrogen peroxide increases and this can lead to soft tissue burns and irritation within the mouth leading to inflammation and redness which can sometimes lead to bleeding.. Therefore, it is important to consult with a dentist before you decide to use hydrogen ...
A rapid, simple, accurate, and sensitive visible spectrophotometric method for the determination of trace amounts of hydrogen peroxide in acidic buffer medium is reported. The proposed method is based on the oxidative coupling of Ampyrone with dibenzazepin hydrochloride by hydrogen peroxide in the buffer medium of pH 4.0 which is catalyzed by ferrous iron. The blue-colored product formed with maximum absorption at 620 nm was found to be stable for 2 h. Beers law is obeyed for hydrogen peroxide concentration in the range of 0.03--0.42 μg ml−1. The optimum reaction conditions and other important optical parameters are reported. The molar absorptive and Sandells sensitivity are found to be 5.89þinspace×þinspace104 mol−1 cm−1 and 0.57 g/cm2, respectively. The interference due to diverse ions and complexing agents was studied.

Hydrogen peroxide is a staple in almost everyones medicine cabinet. And after cuts and scrapes most people run for the hydrogen peroxide to clean their wound. But theres a common misconception that hydrogen peroxide is a disinfectant or antiseptic helpful for treating wounds. Thats not surprising since the label on this bottle of hydrogen peroxide even says, First Aid Antiseptic! While it is an effective cleaning agent, hydrogen peroxide is not actually effective at reducing bacterial infection of wounds. And on the flip side, what most people dont know is that it can cause scarring because its toxic to and even destroys newly formed skin cells.. So whats the story? Should you use Hydrogen peroxide or not?. Well. It depends.. Hydrogen peroxide should be used to help clean dirty wounds, especially those with visible dirt or other foreign material in them, like skinned knees. Thats because its bubbling helps painlessly remove small particles of dirt, gravel and debris acquired by an ...
Abstract: Influence of oxidative stress induced by exogenous application of hydrogen peroxide on initial leaf and coleoptile growth in etiolated wheat seedlings was studied. Leaf and coleoptile growth parameters (mean fresh weight and length) showed a transient stress effect during very initial age, becoming non-significant (P>0.05) in later age (8th day). Mean leaf fresh weight increased steadily after 5th day in both stressed and control seedlings, however the magnitude was lower in stressed seedlings and the difference was non-significant (p>0.05). Mean coleoptile fresh weight was significantly ( ...

Background: HIV-1 infected individuals are under chronic exposure to reactive oxygen species (ROS) considered to be instrumental in the progression of AIDS and the development of HIV-1 associated dementia (HAD). Astrocytes support neuronal function and protect them against cytotoxic substances including ROS. The protein HIV-1 Nef, a progression factor in AIDS pathology is abundantly expressed in astrocytes in patients with HAD, and thus may influence its functions. Results: Endogenous expressed HIV-1 Nef leads to increased sensitivity of human astrocytes towards exogenous hydrogen peroxide but not towards TNF-alpha. Cell death of nef-expressing astrocytes exposed to 10 mu M hydrogen peroxide for 30 min occurred within 4 h. Conclusion: HIV-1 Nef may contribute to neuronal dysfunction and the development of HAD by causing death of astrocytes through decreasing their tolerance for hydrogen peroxide. ...
We currently treat some of our slides, such as kappa and B and T cell markers, with hydrogen peroxide prior to staining to reduce the background staining that we were getting.

Catalase is located in a cell organelle called the peroxisome. Peroxisomes in animal cells are involved in the oxidation of fatty acids, and the synthesis of cholesterol and bile acids. Hydrogen peroxide is a byproduct of fatty acid oxidation. White blood cells produce hydrogen peroxide to kill bacteria. In both cases catalase prevents the hydrogen peroxide from harming the cell itself. Peroxisomes in plant cells are involved in photorespiration (the use of oxygen and production of carbon dioxide) and symbiotic nitrogen fixation (the breaking apart of the nitrogen molecule N2 to reactive nitrogen atoms). Hydrogen peroxide is produced as an intermediate during these chemical processes and must be removed to prevent damage to cellular machinery. Aerobic (oxygen requiring) bacteria produce hydrogen peroxide as a byproduct of metabolism. This fact is used when identifying bacteria. If hydrogen peroxide is added to a bacterial colony and bubbles are produced, this is evidence of oxygen production and ...

eng] Hydrogen peroxide molecules play a significant role in controlling certain cellular functions, and its excess causes significant damage to biological systems. There is experimental evidence that its decomposition is accelerated above phospholipids membranes surface. We propose a mechanism for decomposition of hydrogen peroxide on amino-phospholipids surface model based in Dmol3/DFT calculations. The model was built using periodic boundary conditions. Each unit cell contained two phospholipids molecules, two hydrogen peroxide molecules, and nine water molecules. In the studied reaction, two hydrogen peroxide molecules react in a bimolecular reaction to yield an oxygen molecule and two waters. The reaction proceeds by two steps. In the first step, an intermediate hydrogen trioxide from two H2O2 molecules is formed. In the second step, this intermediate is cleaved in O2 and H2O. There are proton exchanges along the interface between water and amine-phospholipids monolayer in all parts of the ...
Hydrogen peroxide induces oxidation and consequently inactivation of several proteins tyrosine phosphatases. [2]. The cysteine residue localized in the catalytic middle exists within a thiolate anion type and is vunerable to oxidation. 223666-07-7 Oxidation from the cysteine residue, resulting in inactivation from the enzyme, plays a part in the reversible development of sulfenic 223666-07-7 acidity residue. Highly oxidizing circumstances can further induce oxidation towards the sulfinic and sulfonic acidity residues, which is known as irreversible under physiological circumstances [3]. Hydrogen peroxide can be an endogenous signaling agent and will regulate the experience of proteins tyrosine phosphatases via oxidation from the catalytic cysteine residue. Inactivation of the enzymes by hydrogen peroxide could be reversed by mobile reducing agents such as for example glutathione [4]. Hydrogen peroxide in the current presence of carboxylic acids can transform right into a stronger oxidant C a ...
