Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures.
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

Inhibitory innervation of cat sphincter of Oddi. (1/6000)

1 Electrical stimulation with trains of 0.1-0.2 ms pulses of the cat isolated sphincter of Oddi inhibited the spontaneous contractile activity and lowered base-line tension considerably. A contraction usually followed the period of stimulation. 2 These inhibitory effects were prevented by tetrodotoxin 0.1-0.5 mug/ml but were not reduced by hexamethonilm, morphine, or blockade of alpha- or beta-adrenoreceptors of cholinoceptors with phenoxy-benzamine propranolol or atropine, respectively. 3 Adenosine-5'-triphosphate (ATP) and adenosine-5'-diphosphate (ADP) inhibited the spontaneous sphincter activity and caused relaxation thus mimicking the effects of the C-terminal octapeptide of cholecystokinin (C8-CCK), isoprenaline and prostaglandin E1 and E2. 4 ATP alone (greater than 100 mug/ml) or ATP (greater than 10 mug/ml) plus dipyridamole (1 mug/ml), relaxed the sphincter to the same degrees as did the field stimulation. 5 In sphincter maximally contracted by acetylcholine, the effect of stimulation was more marked than that recorded in uncontracted preparations. 6 The present findings suggest that the sphincter of Oddi receives inhibitory nerves that are neither cholinergic nor adrenergic.  (+info)

Conformational changes generated in GroEL during ATP hydrolysis as seen by time-resolved infrared spectroscopy. (2/6000)

Changes in the vibrational spectrum of the chaperonin GroEL in the presence of ADP and ATP have been followed as a function of time using rapid scan Fourier transform infrared spectroscopy. The interaction of nucleotides with GroEL was triggered by the photochemical release of the ligands from their corresponding biologically inactive precursors (caged nucleotides; P3-1-(2-nitro)phenylethyl nucleotide). Binding of either ADP or ATP induced the appearance of small differential signals in the amide I band of the protein, sensitive to protein secondary structure, suggesting a subtle and localized change in protein conformation. Moreover, conformational changes associated with ATP hydrolysis were detected that differed markedly from those observed upon nucleotide binding. Both, high-amplitude absorbance changes and difference bands attributable to modifications in the interaction between oppositely charged residues were observed during ATP hydrolysis. Once this process had occurred, the protein relaxed to an ADP-like conformation. Our results suggest that the secondary structure as well as salt bridges of GroEL are modified during ATP hydrolysis, as compared with the ATP and ADP bound protein states.  (+info)

Magnesium ion-induced changes in the binding mode of adenylates to chloroplast coupling factor 1. (3/6000)

The effect of Mg2+ on the binding of adenylates to isolated chloroplast coupling factor 1 (CF1) was studied using CD spectrometry and ultrafiltration. At adenylate concentrations smaller than 100 muM, one mole of CF1 binds three moles of ATP (or ADP) regardless of the presence of Mg2+. In the presence of Mg2+, the first two ATP's bind to CF1 independently with the same binding constant of 2.5 X 10(-1) muM-1, then the third ATP binds with a much higher affinity of 10 muM-1. In the absence of Mg2+, the first ATP binds to CF1 with a binding constant of 2.5 X 10(-1) muM-1 then the other two ATP's bind less easily with the same binding constant of 4.0 X 10(-2) muM-1. The binding mode of ADP to CF1 is quite similar to that of ATP. In the presence of Mg2+, the binding constants of the first two ADP's are both 7.6 X 10(-2) muM-1, that of the third ADP being 4.0 muM-1. In the absence of Mg2+, the binding constant of the first ADP is 7.6 X 10(-2) muM-1, the constants of the other two ADP's both being 4.0 X 10(-2) muM-1. AMP caused a negligible change in CD.  (+info)

Mutations of Arg198 in sarcoplasmic reticulum Ca2+-ATPase cause inhibition of hydrolysis of the phosphoenzyme intermediate formed from inorganic phosphate. (4/6000)

Arg198 of sarcoplasmic reticulum Ca2+-ATPase was substituted with lysine, glutamine, glutamic acid, alanine, and isoleucine by site-directed mutagenesis. Kinetic analysis was performed with microsomal membranes isolated from COS-1 cells which were transfected with the mutated cDNAs. The rate of dephosphorylation of the ADP-insensitive phosphoenzyme was determined by first phosphorylating the Ca2+-ATPase with 32Pi and then diluting the sample with non-radioactive Pi. This rate was reduced substantially in the mutant R198Q, more strongly in the mutants R198A and R1981, and most strongly in the mutant R198E, but to a much lesser extent in R198K. The reduction in the rate of dephosphorylation was consistent with the observed decrease in the turnover rate of the Ca2+-ATPase accompanied by the steady-state accumulation of the ADP-insensitive phosphoenzyme formed from ATP. These results indicate that the positive charge and high hydrophilicity of Arg198 are critical for rapid hydrolysis of the ADP-insensitive phosphoenzyme.  (+info)

Nitric oxide inhibits cardiac energy production via inhibition of mitochondrial creatine kinase. (5/6000)

Nitric oxide biosynthesis in cardiac muscle leads to a decreased oxygen consumption and lower ATP synthesis. It is suggested that this effect of nitric oxide is mainly due to the inhibition of the mitochondrial respiratory chain enzyme, cytochrome c oxidase. However, this work demonstrates that nitric oxide is able to inhibit soluble mitochondrial creatine kinase (CK), mitochondrial CK bound in purified mitochondria, CK in situ in skinned fibres as well as the functional activity of mitochondrial CK in situ in skinned fibres. Since mitochondrial isoenzyme is functionally coupled to oxidative phosphorylation, its inhibition also leads to decreased sensitivity of mitochondrial respiration to ADP and thus decreases ATP synthesis and oxygen consumption under physiological ADP concentrations.  (+info)

Depolarization-evoked Ca2+ release in a non-excitable cell, the rat megakaryocyte. (6/6000)

1. The effect of membrane potential on [Ca2+]i in rat megakaryocytes was studied using simultaneous whole-cell patch clamp and fura-2 fluorescence recordings. 2. Depolarization from -75 to 0 mV had no effect on [Ca2+]i in unstimulated cells, but evoked one or more spikes of Ca2+ increase (peak increase: 714 +/- 95 nM) during activation of metabotropic purinoceptors by 1 microM ADP. 3. The depolarization-evoked Ca2+ increase was present in Ca2+-free medium and also following removal of Na+. Thus depolarization mobilizes Ca2+ from an intracellular store without a requirement for altered Na+-Ca2+ exchange activity. 4. Intracellular dialysis with heparin blocked the depolarization-evoked Ca2+ increase, indicating a role for functional IP3 receptors. 5. Under current clamp, ADP caused the membrane potential to fluctuate between -43 +/- 1 and -76 +/- 1 mV. Under voltage clamp, depolarization from -75 to -45 mV evoked a transient [Ca2+]i increase (398 +/- 91 nM) during exposure to ADP. 6. We conclude that during stimulation of metabotropic purinoceptors, membrane depolarization over the physiological range can stimulate Ca2+ release from intracellular stores in the rat megakaryocyte, a non-excitable cell type. This may represent an important mechanism by which electrogenic influences can control patterns of [Ca2+]i increase.  (+info)

Platelet aggregation and incident ischaemic heart disease in the Caerphilly cohort. (7/6000)

BACKGROUND: Platelets are involved in myocardial infarction but evidence of prediction of infarction by measures of platelet function are sparce. METHODS: Platelet aggregation to thrombin and to ADP in platelet rich plasma was recorded for 2176 men aged 49-65 years in the Caerphilly cohort study. RESULTS: Results from 364 men were excluded, 80 of whom had not fasted before venepuncture; most of the others were excluded because antiplatelet medication had been taken shortly before the platelet tests. During the five years following the platelet tests 113 ischaemic heart disease (IHD) events which fulfilled the World Health Organisation criteria were identified--42 fatal and 71 non-fatal. No measure of platelet aggregation was found to be significantly predictive of incident IHD. The possibility that platelet function is predictive for only a limited time after it is characterised, and that prediction falls off with time, was tested. When IHD events are grouped by their time of occurrence after aggregation had been measured, the test results show a gradient suggestive of prediction of early IHD events. Thus, 24% of the men who had an event within 500 days of the test had had a high secondary response to ADP while only 12% of those whose IHD event had been 1000 or more days after the test had shown a high platelet response at baseline. The trend in these proportions is not significant. CONCLUSIONS: Platelet aggregation to thrombin and ADP in platelet rich plasma was recorded in the Caerphilly cohort study. No measure of aggregation was found to be predictive of IHD.  (+info)

Binding of the transition state analog MgADP-fluoroaluminate to F1-ATPase. (8/6000)

Escherichia coli F1-ATPase from mutant betaY331W was potently inhibited by fluoroaluminate plus MgADP but not by MgADP alone. beta-Trp-331 fluorescence was used to measure MgADP binding to catalytic sites. Fluoroaluminate induced a very large increase in MgADP binding affinity at catalytic site one, a smaller increase at site two, and no effect at site three. Mutation of either of the critical catalytic site residues beta-Lys-155 or beta-Glu-181 to Gln abolished the effects of fluoroaluminate on MgADP binding. The results indicate that the MgADP-fluoroaluminate complex is a transition state analog and independently demonstrate that residues beta-Lys-155 and (particularly) beta-Glu-181 are important for generation and stabilization of the catalytic transition state. Dicyclohexylcarbodiimide-inhibited enzyme, with 1% residual steady-state ATPase, showed normal transition state formation as judged by fluoroaluminate-induced MgADP binding affinity changes, consistent with a proposed mechanism by which dicyclohexylcarbodiimide prevents a conformational interaction between catalytic sites but does not affect the catalytic step per se. The fluorescence technique should prove valuable for future transition state studies of F1-ATPase.  (+info)

The effect of long-chain acyl-CoA on subcellular adenine nucleotide systems was studied in the intact liver cell. Long-chain acyl-CoA content was varied by varying the nutritional state (fed and starved states) or by addition of oleate. Starvation led to an increase in the mitochondrial and a decrease in the cytosolic ATP/ADP ratio in liver both in vivo and in the isolated perfused organ as compared with the fed state. The changes were reversed on re-feeding glucose in liver in vivo or on infusion of substrates (glucose, glycerol) in the perfused liver, respectively. Similar changes in mitochondrial and cytosolic ATP/ADP ratios occurred on addition of oleate, but, importantly, not with a short-chain fatty acid such as octanoate. It is concluded that long-chain acyl-CoA exerts an inhibitory effect on mitochondrial adenine nucleotide translocation in the intact cell, as was previously postulated in the literature from data obtained with isolated mitochondria. The physiological relevance with ...

The second mechanism of respiratory control (allosteric ATP-inhibition of cytochrome c oxidase (CcO)) is demonstrated for the first time in intact isolated rat liver and heart mitochondria. The problems of measuring the kinetics of allosteric ATP-inhibition in isolated mitochondria were investigated. And it was found that only at very high ATP/ADP ratios, this inhibition is obtained and requires an ATP-regenerating system consisting of phosphoenolpyruvate (PEP) and pyruvate kinase (PK). The allosteric ATP-inhibition can be switched off probably by dephosphorylation of a serine at CcO subunit-I. The phosphorylation of CcO at serine, threonine and tyrosine was studied in isolated mitochondria by extracting complex IV of the respiratory chain (CcO) by BN-PAGE (blue-nativepolyacrylamide- gel-electrophoresis), SDS-PAGE and Western blotting with the corresponding antibodies against the phosphorylated amino acids. The extent of allosteric ATP-inhibition of CcO varied in different preparations of ...

BioAssay record AID 336312 submitted by ChEMBL: Antiplatelet activity against bovine citreated platelet assessed as inhibition of ADP-induced platelet aggregation up to 278 ug/ml after 6 mins.
flects ATP hydrolysis. This reduction is accompanied by a rise of intracellular ADP content and a decrease in ATP/ADP ratio, respectively. However, in parallel with the ongoing slight reduction of intracellular ATP level, the intracellular AMP content gradually raises. The regulatory significance of ATP/ADP ratio gradually decreases and becomes replaced by the control of ATP synthesis through the ATP/AMP ratio. At the last stage of hypoxia, when a linear decrease in ATP content is observed, the regulatory role of ATP/ADP and ATP/AMP ratios becomes minimal, and total adenine nucleotides plus energetic charges decrease [3,9]. The hypoxia-induced changes in adenine nucleotides pool resulting from disturbed electron flow and oxidative phosphorylation reactions precede changes in other functional and metabolic parameters responsible for the cell vital activity. Contrastingly, the compensatory role of glycolysis as an ATP supplier is effective only in early hypoxia. During the terminal period, despite ...
The effect of MgADP on the sarcomere length (SL) dependence of tension generation was investigated using skinned rat ventricular trabeculae. Increasing SL from 1.9 to 2.3 microm decreased the muscle width by approximately 11% and shifted the midpoint of the pCa-tension relationship (pCa(50)) leftward by about 0.2 pCa units. MgADP (0.1, 1, and 5 mmol/L) augmented maximal and submaximal Ca(2+)-activated tension and concomitantly diminished the SL-dependent shift of pCa(50) in a concentration-dependent manner. In contrast, pimobendan, a Ca(2+) sensitizer, which promotes Ca(2+) binding to troponin C (TnC), exhibited no effect on the SL-dependent shift of pCa(50), suggesting that TnC does not participate in the modulation of SL-dependent tension generation by MgADP. At a SL of 1. 9 microm, osmotic compression, produced by 5% wt/vol dextran (molecular weight approximately 464 000), reduced the muscle width by approximately 13% and shifted pCa(50) leftward to a similar degree as that observed when increasing

In total,116 patients were prospectively enrolled with a stable cardiovascular disease, taking ASA 100 mg/day for |or=1 month. The control group consisted of 62 healthy volunteers. A platelet aggregation was investigated by optical aggregometry (aggregometer LASER 4x; BIO ART, Sint-Katelijne-Waver, Belgium). CPG and ADP were added as aggregating agents. The measured parameters were CPG-slope (%/min) and ADP max (%). Using the CPG-slope values from the control group, the CPG-slope cut-off value was determined to define a laboratory ASA-noneffectively treated patient. The values from control group followed a normal distribution (Shapiro-Wilk test). We calculated the cut-off value using the 1-tailed 95% confidence interval. The CPG-slope cut-off value was 79 %/min for an ASA-effectively treated patient. We marked the
The human body is powered, essentially, by a substance called Adenosine Triphosphate (ATP). This substance is regarded as the energy unit of life. To use this energy source to, for example, contract a muscle, ATP is converted to Adenosine Diphosphate (ADP), resulting in a release of energy. Over time, ADP can be converted back into ADT using the energy obtained from food. ATP can be regarded as the charged state, and ADP can be regarded as the discharged state of a battery.. This process could be used in two ways.. Firstly, it may be possible to create an Organic Battery which converts chemical energy from this process into electrical energy. I found THIS link which seems to indicate that some work is already being done on this process. The only questions would be regarding how small such a power source could be, how efficient the energy transfer would be, and how the battery could be recharged in real-world conditions. This could potentially solve a difficult engineering problem, ...
Intravenous and oral administration of a chemically stable carboprostacyclin analogue, 15-cyclopentyl-ω-pentanor-5(E)-carbacyclin (ONO 41483), resulted in ex-vivo inhibition of ADP-induced platelet aggregation in man. The maximum tolerated intravenous dose was 2.5 ng/kg/min for 1 hour and this produced a mean of 27.1% inhibition in 3 volunteers. For oral administration the tolerated single dose was 200 μg. At this dose, there was 56.3% inhibition of aggregation (mean of 3 results). High oral (400 μg) and intravenous doses (5 and 10 ng/kg/min for 1 hour) of ONO 41483, which caused marked inhibition of aggregation (ranging 39-100%), was accompanied by flushing of face and extremities, headache and phlebitis. However, none of the doses tested produced significant changes in arterial blood pressure or heart rate ...
Approach and Results-Our goal is to determine whether a novel antibody targeting the ligand-binding domain, ie, second extracellular loop (EL2) of the P2Y1R (EL2Ab) could inhibit platelet function and protect against thrombogenesis. Our results revealed that the EL2Ab does indeed inhibit ADP-induced platelet aggregation, in a dose-dependent manner. Furthermore, EL2Ab was found to inhibit integrin GPIIb-IIIa activation, dense and α granule secretion, and phosphatidylserine exposure. These inhibitory effects translated into protection against thrombus formation, as evident by a prolonged time for occlusion in a FeCl3-induced thrombosis model, but this was accompanied by a prolonged tail bleeding time. We also observed a dose-dependent displacement of the radiolabeled P2Y1R antagonist [3H]MRS2500 from its ligand-binding site by EL2Ab. ...

PDRP is an unusual bifunctional ADP-dependent phosphotransferase involved in the regulation of C4 plant photosynthesis. Despite thirty years of research since its discovery, biophysical, kinetic, and structural characterisations have remained elusive. The discovery of a homologous protein (YdiA) in E. coli provides an unparalleled opportunity to obtain such characterisations. For the first time, YdiA has been cloned, overexpressed, and the biophysical characteristics have been determined. The protein was found to be dimeric by gel filtration, native-PAGE, and AUC. ITC was used to characterise binding affinity for the putative substrates. The protein binds in a largely temperature and pH-independent manner to ADP, AMP, phosphate, and pyrophosphate, in the uM range, with KdS of \.24 ± 0. 76, 5.23 ± l.l0, 15.54 ± 4.30, and 24.18 ± 2.70 respectively.

The primary role of creatine is recharging ATP, by donating a phosphate ion to the ADP molecule. Muscle fibres generate tension by cutting off a phosphate group from ATP (charged form), turning it into ADP (uncharged from).. Three energy systems provide energy to recharge ADP back into ATP: the ATP-phosphocreatine system, the lactic acid system and the aerobic system. The percentage each energy system contributes depends on the intensity and duration of the activity.. The ATP-phosphocreatine system is the major energy provider for high-intense, explosive actions. This system is limited however by the amount of phosphocreatine that is stored in the muscles. After approximately 10 seconds of high-intense activity all the phosphocreatine is depleted and the ATP-phosphocreatine system can no longer contribute to energy production (recharging ADP into ATP) until it is replenished (approximately 3 minutes of rest). The power output drops when phosphocreatine levels in the muscle cells gets depleted, ...

Energy for this comes from ATP, the energy source of the cell. ATP binds to the cross bridges between myosin heads and actin filaments. The release of energy powers the swiveling of the myosin head.

Muscle tissue also contains a stored supply of a fast acting recharge chemical, creatine phosphate which can assist initially producing the rapid regeneration of ADP into ATP ...

A method for forming a MEMS device is disclosed, where a final release step is performed just prior to a wafer bonding step to protect the MEMS device from contamination, physical contact, or other deleterious external events. Without additional changes to the MEMS structure between release and wafer bonding and singulation, except for an optional stiction treatment, the MEMS device is best protected and overall process flow is improved. The method is applicable to the production of any MEMS device and is particularly beneficial in the making of fragile micromirrors.

The present study clarifies several aspects of the effects on platelet aggregation of arising and assuming the upright posture in the morning: 1) On arising, increased platelet aggregation can readily be observed in whole blood; 2) this increased aggregation is not accompanied by platelet activation, as evidenced by changes in activation-dependent markers on the platelet surface; 3) the observed increase in aggregation in whole blood may be partly explained by increases in platelet count and hematocrit that accompany arising. In addition, the study confirmed previous reports of increased fibrinolysis on standing and provided new evidence of an opposing increase in thrombin generation on standing.. Comparison with previous studies. Studies reporting the effects of arising in the morning on platelet aggregation (7-11,13) have exclusively studied aggregation in PRP, and to our knowledge, the present study is the first to report the effects of arising on platelet aggregation in whole blood. Of the ...
The thienopyridine anti-platelet drugs, such as clopidogrel, require metabolic activation in vivo to effectively block platelet aggregation. The study of the activation of these compounds has been hampered by the lability and reactivity of the ring-opened active metabolite. Many studies have relied solely on the disappearance of the parent drug as an indicator of bioactivation by a particular cytochrome P450 (CYP). We have developed an alternative method for studying the formation of the active metabolite. Conditions were optimized whereby washed human platelets can be incubated in the presence of an individual, recombinant CYP and clopidogrel. At various time points during this incubation, an aliquot is removed and platelet aggregation is measured using 2-(Methylthio)adenosine 5′-diphosphate (2MeSADP) or adenosine 5′-diphosphate (ADP) as the agonist. Inhibition of platelet aggregation, compared to the control lacking active enzyme, suggests the formation of the thienopyridine active ...
An uncoupling protein (UCP) is a mitochondrial inner membrane protein that is a regulated proton channel or transporter. An uncoupling protein is thus capable of dissipating the proton gradient generated by NADH-powered pumping of protons from the mitochondrial matrix to the mitochondrial intermembrane space. The energy lost in dissipating the proton gradient via UCPs is not used to do biochemical work. Instead, heat is generated. This is what links UCP to thermogenesis. UCPs are positioned in the same membrane as the ATP synthase, which is also a proton channel. The two proteins thus work in parallel with one generating heat and the other generating ATP from ADP and inorganic phosphate, the last step in oxidative phosphorylation. Mitochondria respiration is coupled to ATP synthesis (ADP phosphorylation) but is regulated by UCPs. There are five types of homologs known in mammals: UCP1, also known as thermogenin UCP2 UCP3 SLC25A27, also known as UCP4 SLC25A14, also known as UCP5 Uncoupling ...

The kit is intended for determination of intracellular ATP (adenosine triphosphate) in living cells. Extracellular ATP in the samples is enzymatically degraded. If the samples also contain somatic cells and the intention is to determine microbial ATP, we recommend 266-112 Microbial ATP Kit including a Cell Lysing Reagent for most animal cells. 266-311 ATP Biomass Kit can be used, if there is only one type of cells and no extracellular ATP in the samples. All living cells contain ATP where it plays the role of energy currency between different cellular processes. When cells die of natural causes, ATP is normally degraded. The intracellular concentration of ATP is carefully regulated to similar levels in all types of cells. ATP is therefore a good estimate of the total intracellular volume. Most bacterial cells contain approx. 2×10 -18 mol ATP per cell, while most eukaryotic cells, as a result of their larger size, contain 10 -15 mol ATP or more. ATP Biomass Kit HS, Intracellular ATP Kit HS and ...

ATP je sestavljen iz adenozina (adeninski obroč, povezan s sladkorjem ribozo) in treh fosfatnih skupin (trifosfat). Fosfatne skupine označujemo z alfa (α), beta (β) in gama (γ) glede na njihovo oddaljenost od riboze, začenši s fosfatno skupino alfa, ki je najbližje ribozi. ATP je dobro topen v vodi in dokaj stabilen v območju pH od 6,8 do 7,4, medtem ko pri ekstremnih vrednostih pH hitro poteče hidroliza. ATP je tako najbolje shranjevati v obliki brezvodne soli. ATP v nepufrani vodi razpade na ADP in fosfat. To je posledica šibkejših vezi med fosfatnimi skupinami znotraj molekule ATP v primerjavi z vodikovimi vezmi, ki se vzpostavijo med produkti hidrolize ATP (ADP + fosfat) in vodo. ATP in ADP sta v vodi v kemijskem ravnotežju (večina je v obliki ADP). Sistem, ki je oddaljen od ravnotežja, vsebuje Gibbsovo prosto energijo in je sposoben opravljanja delo. Celice vzdržujejo razmerje ATP/ADP približno 10 velikostnih razredov stran od ravnotežja, kar pomeni, da je koncentracija ...
