Streszczenie:

The effects of a whole series of adenine nucleotides on Ins(1,4,5)P3-induced Ca2+ release were characterized in permeabilized A7r5 smooth-muscle cells. Several adenine nucleotides activated the Ins(1,4,5)P3 receptor. It was observed that 3′-phosphoadenosine 5′-phosphosulphate, CoA, di(adenosine-5′)tetraphosphate (Ap4A) and di(adenosine-5′)pentaphosphate (Ap5A) were more effective than ATP. Ap4A and Ap5A also interacted with a lower EC50 than ATP. In order to find out how these adenine nucleotides affected Ins(1,4,5)P3-induced Ca2+ release, we have measured their effect on the response of perme

Streszczenie:

A recently proposed chemomechanical group transfer theory of rotary biomolecular motors is applied to treat single-molecule controlled rotation experiments. In these experiments, single-molecule fluorescence is used to measure the binding and release rate constants of nucleotides by monitoring the occupancy of binding sites. It is shown how missed events of nucleotide binding and release in these experiments can be corrected using theory, with F1-ATP synthase as an example. The missed events are significant when the reverse rate is very fast. Using the theory the actual rate constants in the c

High-affinity 3,3′,5-tri-iodo-L-thyronine (T3) binding (Kd approximately 0.3 nM) to the cytosol of cultured rat astroglial cells was strongly activated in the presence of pyridine nucleotides. A 35 kDa pyridine nucleotide-dependent T3-binding polypeptide (35K-TBP) was photoaffinity labelled using underivatized [125I]T3 in the presence of pyridine nucleotides and the free-radical scavenger dithiothreitol. Maximum activations of T3 binding and 35K-TBP photolabelling were obtained at approx. 1 x 10(-7) M NADP+ or NADPH, or 1 x 10(-4) M NADH. NAD+ and other nucleotides were without effect. NADPH i

Adenosine, ATP, and various nucleotides were examined for their effects on the adherence of leukocytes to bovine pulmonary artery endothelial cells. Extracellular ATP enhanced adherence of HL-60 cells and human neutrophils to endothelial cells in a dose-dependent fashion. Maximal adherence occurred after 15 min coincubation of ATP and HL-60 cells or neutrophils with endothelial cells. ATP stimulation was mediated by direct effects on both HL-60 cells and endothelial cells. The potency profile of various nucleotides was ATP = 2-MeSATP > beta,gamma-CH2ATP, indicative of a P2y receptor. Intere

Fluorescence stopped-flow experiments were performed to elucidate the elementary steps of the ATPase mechanism of scallop heavy meromyosin in the presence and in the absence of Ca2+. ATP binding and hydrolysis, as monitored by the change in tryptophan fluorescence, appear to be Ca2+-insensitive, whereas both Pi release and ADP release are markedly suppressed in the absence of Ca2+. Rate constants for Pi release are 0.2 s-1 and 0.002 s-1 and for ADP release are 6 s-1 and 0.01 s-1 in the presence and in the absence of Ca2+ respectively.

Complexation of biopolymers with halloysite nanotubes (HNTs) can greatly affect their applicability as materials building blocks. Here we have performed a systematic investigation of fabrication of halloysite nanotubes complexes with nucleotides and genomic DNA. The binding of DNA and various nucleotide species (polyAU, UMP Na2, ADP Na3, dATP Na, AMP, uridine, ATP Mg) by halloysite nanotubes was tested using UV-spectroscopy. The study revealed that binding of different nucleotides to the nanoclay varied but was low both in the presence and absence of MgCl2, while MgCl2 facilitated significantl

Streszczenie:

Ca2+ release from intracellular stores occurs via two families of intracellular channels, each with their own specific agonist: Ins(1,4,5)P3 for the Ins(1,4,5)P3 receptor and cyclic ADP-ribose (cADPR) for the ryanodine receptor. We now report that cADPR inhibited Ins(1,4,5)P3-induced Ca2+ release in permeabilized A7r5 cells with an IC50 of 20 μM, and in permeabilized 16HBE14o- bronchial mucosal cells with an IC50 of 35 μM. This inhibition was accompanied by an increase in specific [3H]Ins(1,4,5)P3 binding. 8-Amino-cADPR, but not 8-bromo-cADPR, antagonized this effect of cADPR. The inhibition w

The guanine nucleotide binding properties of rap1 protein purified from human neutrophils were examined using both the protein kinase A-phosphorylated and the non-phosphorylated forms of the protein. Binding of GTP[S] (guanosine 5′-[gamma-thio]triphosphate) or GDP was found to be slow in the presence of free Mg2+, but very rapid in the absence of Mg2+. The binding of guanine nucleotides was found to correlate with the loss of endogenous nucleotide from the rap1 protein, which was rapid in the absence of Mg2+. The relative affinities of GTP and GDP for the binding site on rap1 were modulated by

We examined the effects of guanine nucleotides on the interaction of the 44 kDa form with the plasma membrane.

Synaptic vesicle protein 2 (SV2) is a transporter-like protein specifically expressed in endocrine cells and neurons, where it is localized to vesicles that undergo regulated secretion and plays an essential role in regulating neurotransmitter release. SV2 binds adenine nucleotides including ATP. Analysis of ATP transport revealed that SV2 is not an ATP transporter, nor does it affect ATP transport. As a further step toward understanding how ATP binding contributes to SV2 function, we investigated whether SV2 is an ATPase using an in vitro measure of ATPase activity. The study reported here in

GTPases are found in all domains of life and are highly conserved. In eukaryotes, they serve as signalling molecules for many cellular processes. However, the prokaryotic GTPases play a very different role and are found to be associated with ribosome function. Among the 11 conserved GTPases, Der is the most interesting in prokaryotes. It possesses a unique structure with two GTPase domains (G-Domains) tethered by a variable length acidic linker and a carboxyl terminal KH-like domain. The exact function of Der is still under investigation and most of the data suggest that it is important for 50

A 17-year-old Italian boy has had a lifelong bleeding tendency, with frequent epistaxes and gum bleeding. The bleeding time is prolonged and the platelet count low normal. Electron microscopy showed a wide diversity of platelet size with many giant forms. In citrated PRP, ADP and other agonists induce slow and incomplete aggregation. The response of washed platelets varied with the agonist but ranged from subnormal to almost normal. Fibrinogen binding to washed platelets occurred slowly in response to ADP but eventually approached normal levels. No significant abnormality was observed of 5HT u

The effects of fluoride at mM concentrations on prostacyclin (PGI2) production by human umbilical vein endothelial cells in culture were investigated. At lower concentrations, with a peak activity around 20-30 mM, sodium fluoride (NaF) caused a slow rise in PGI2 release reaching a maximum of 6 to 8 × control values after 1 hour. With increasing concentrations, the NaF-induced PGI2 production progressively decreased to almost control levels at 100 mM. Preincubation of the cells with 100 mM NaF inhibited thrombin— and A23187-stimulated PGI2 production by 46 % and 64 % respectively. The response

It is now widely recognized that the activation of phospholipase C by specific agonists leads to the formation of two second messengers: (1) inositol trisphosphate, which releases Ca2+ from the endoplasmic reticulum to the cytosol and (2) 1,2- diacylglycerol, which stimulates protein kinase C. In the past few years, GTP-binding proteins have been associated with the regulation of phospholipase C. However, the identity of the GTP-binding protein involved and the type of association with phospholipase C is not yet known. It is now recognized that there are two types of phospholipase C enzymes: (

Certain ligand-receptor interactions at cell surfaces lead to the phospholipase-C (PLC) hydrolysis of phosphatidyl inositol (4.5) bisphosphate (PIP2). The products serve as intracellular second messengers, e.g. inositol (1.4.5) trisphosphate (IP3) releases Ca2+ from intracellular stores and diacylglycerol activates protein kinase-C. From studies using GTP and analogues (e.g. GTPγS) there is evidence of a key role for a guanine nucleotide binding protein(s) as a link between receptors and PIP2 hydrolysis. We report the actions of GTPγS on washed human platelets permeabilised with saponin (12-14
