Membrane deinsertion of SecA underlying proton motive force-dependent stimulation of protein translocation. (1/12201)

The proton motive force (PMF) renders protein translocation across the Escherichia coli membrane highly efficient, although the underlying mechanism has not been clarified. The membrane insertion and deinsertion of SecA coupled to ATP binding and hydrolysis, respectively, are thought to drive the translocation. We report here that PMF significantly decreases the level of membrane-inserted SecA. The prlA4 mutation of SecY, which causes efficient protein translocation in the absence of PMF, was found to reduce the membrane-inserted SecA irrespective of the presence or absence of PMF. The PMF-dependent decrease in the membrane-inserted SecA caused an increase in the amount of SecA released into the extra-membrane milieu, indicating that PMF deinserts SecA from the membrane. The PMF-dependent deinsertion reduced the amount of SecA required for maximal translocation activity. Neither ATP hydrolysis nor exchange with external SecA was required for the PMF-dependent deinsertion of SecA. These results indicate that the SecA deinsertion is a limiting step of protein translocation and is accelerated by PMF, efficient protein translocation thereby being caused in the presence of PMF.  (+info)

Stable remodeling of tailless nucleosomes by the human SWI-SNF complex. (2/12201)

The histone N-terminal tails have been shown previously to be important for chromatin assembly, remodeling, and stability. We have tested the ability of human SWI-SNF (hSWI-SNF) to remodel nucleosomes whose tails have been cleaved through a limited trypsin digestion. We show that hSWI-SNF is able to remodel tailless mononucleosomes and nucleosomal arrays, although hSWI-SNF remodeling of tailless nucleosomes is less effective than remodeling of nucleosomes with tails. Analogous to previous observations with tailed nucleosomal templates, we show both (i) that hSWI-SNF-remodeled trypsinized mononucleosomes and arrays are stable for 30 min in the remodeled conformation after removal of ATP and (ii) that the remodeled tailless mononucleosome can be isolated on a nondenaturing acrylamide gel as a novel species. Thus, nucleosome remodeling by hSWI-SNF can occur via interactions with a tailless nucleosome core.  (+info)

Arginine methylation and binding of Hrp1p to the efficiency element for mRNA 3'-end formation. (3/12201)

Hrp1p is a heterogeneous ribonucleoprotein (hnRNP) from the yeast Saccharomyces cerevisiae that is involved in the cleavage and polyadenylation of the 3'-end of mRNAs and mRNA export. In addition, Hrplp is one of several RNA-binding proteins that are posttranslationally modified by methylation at arginine residues. By using functional recombinant Hrp1p, we have identified RNA sequences with specific high affinity binding sites. These sites correspond to the efficiency element for mRNA 3'-end formation, UAUAUA. To examine the effect of methylation on specific RNA binding, purified recombinant arginine methyltransferase (Hmt1p) was used to methylate Hrp1p. Methylated Hrp1p binds with the same affinity to UAUAUA-containing RNAs as unmethylated Hrpl p indicating that methylation does not affect specific RNA binding. However, RNA itself inhibits the methylation of Hrp1p and this inhibition is enhanced by RNAs that specifically bind Hrpl p. Taken together, these data support a model in which protein methylation occurs prior to protein-RNA binding in the nucleus.  (+info)

The Golgi apparatus plays a significant role in the maintenance of Ca2+ homeostasis in the vps33Delta vacuolar biogenesis mutant of Saccharomyces cerevisiae. (4/12201)

The vacuole is the major site of intracellular Ca2+ storage in yeast and functions to maintain cytosolic Ca2+ levels within a narrow physiological range. In this study, we examined how cellular Ca2+ homeostasis is maintained in a vps33Delta vacuolar biogenesis mutant. We found that growth of the vps33Delta strain was sensitive to high or low extracellular Ca2+. This strain could not properly regulate cytosolic Ca2+ levels and was able to retain only a small fraction of its total cellular Ca2+ in a nonexchangeable intracellular pool. Surprisingly, the vps33Delta strain contained more total cellular Ca2+ than the wild type strain. Because most cellular Ca2+ is normally found within the vacuole, this suggested that other intracellular compartments compensated for the reduced capacity to store Ca2+ within the vacuole of this strain. To test this hypothesis, we examined the contribution of the Golgi-localized Ca2+ ATPase Pmr1p in the maintenance of cellular Ca2+ homeostasis. We found that a vps33Delta/pmr1Delta strain was hypersensitive to high extracellular Ca2+. In addition, certain combinations of mutations effecting both vacuolar and Golgi Ca2+ transport resulted in synthetic lethality. These results indicate that the Golgi apparatus plays a significant role in maintaining Ca2+ homeostasis when vacuolar biogenesis is compromised.  (+info)

Deletion mutation analysis of the mutS gene in Escherichia coli. (5/12201)

The MutS protein is part of the dam-directed MutHLS mismatch repair pathway in Escherichia coli. We have constructed deletion derivatives in the mutS gene, which retain the P-loop coding region for ATP binding. The mutant proteins were assayed for ATP hydrolysis, heteroduplex DNA binding, heterodimer MutS formation, and the ability to interact with MutL. Dimerization was assayed by expressing His6-tagged wild-type and non-tagged deletion mutant proteins in the same cell and isolating the His6-tagged protein followed by MutS immunoblotting after SDS-polyacrylamide gel electrophoresis. MutS-MutL interaction was measured using the same technique except that the MutL protein carried the His6 tag. Our results indicate that DNA binding ability resides in the N-terminal end of MutS, and dimerization and MutL interactions are located in the C-terminal end. Given the extensive amino acid homology in the MutS family our results with E. coli should be applicable to MutS homologues in other prokaryotes and eukaryotes.  (+info)

Evolutionary dynamics of a mitochondrial rearrangement "hot spot" in the Hymenoptera. (6/12201)

The arrangement of tRNA genes at the junction of the cytochrome oxidase II and ATPase 8 genes was examined across a broad range of Hymenoptera. Seven distinct arrangements of tRNA genes were identified among a group of wasps that have diverged over the last 180 Myr (suborder Apocrita); many of the rearrangements represent evolutionarily independent events. Approximately equal proportions of local rearrangements, inversions, and translocations were observed, in contrast to vertebrate mitochondria, in which local rearrangements predominate. Surprisingly, homoplasy was evident among certain types of rearrangement; a reversal of the plesiomorphic gene order has arisen on three separate occasions in the Insecta, while the tRNA(H) gene has been translocated to this locus on two separate occasions. Phylogenetic analysis indicates that this gene translocation is real and is not an artifactual translocation resulting from the duplication of a resident tRNA gene followed by mutation of the anticodon. The nature of the intergenic sequences surrounding this region does not indicate that it should be especially prone to rearrangement; it does not generally have the tandem or inverted repeats that might facilitate this plasticity. Intriguingly, these findings are consistent with the view that during the evolution of the Hymenoptera, rearrangements increased at the same time that the rate of point mutations and compositional bias also increased. This association may direct investigations into mitochondrial genome plasticity in other invertebrate lineages.  (+info)

Characterisation of copper-binding to the second sub-domain of the Menkes protein ATPase (MNKr2). (7/12201)

The Menkes ATPase (MNK) has an essential role in the translocation of copper across cellular membranes. In a complementary manner, the intracellular concentration of copper regulates the activity and cellular location of the ATPase through its six homologous amino-terminal domains. The roles of the six amino-terminal domains in the activation and cellular trafficking processes are unknown. Understanding the role of these domains relies on the development of an understanding of their metal-binding properties and structural properties. The second conserved sub-domain of MNK was over-expressed, purified and its copper-binding properties characterised. Reconstitution studies demonstrate that copper binds to MNKr2 as Cu(I) with a stoichiometry of one copper per domain. This is the first direct evidence of copper-binding to the MNK amino-terminal repeats. Circular dichroism studies suggest that the binding or loss of copper to MNKr2 does not cause substantial changes to the secondary structure of the protein.  (+info)

The interaction of the human MutL homologues in hereditary nonpolyposis colon cancer. (8/12201)

Germline mutations in two human mismatch repair (MMR) genes, hMSH2 and hMLH1, appear to account for approximately 70% of the common cancer susceptibility syndrome hereditary nonpolyposis colorectal cancer (HNPCC). Although the hMLH1 protein has been found to copurify with another MMR protein hPMS2 as a heterodimer, their function in MMR is unknown. In this study, we have identified the physical interaction regions of both hMLH1 with hPMS2. We then examined the effects of hMLH1 missense alterations found in HNPCC kindreds for their interaction with hPMS2. Four of these missense alterations (L574P, K616Delta, R659P, and A681T) displayed >95% reduction in binding to hPMS2. Two additional missense alterations (K618A and K618T) displayed a >85% reduction in binding to hPMS2, whereas three missense alterations (S44F, V506A, and E578G) displayed 25-65% reduction in binding to hPMS2. Interestingly, two HNPCC missense alterations (Q542L and L582V) contained within the consensus interaction region displayed no effect on interaction with hPMS2, suggesting that they may affect other functions of hMLH1. These data confirm that functional deficiencies in the interaction of hMLH1 with hPMS2 are associated with HNPCC as well as suggest that other unknown functional alteration of the human MutL homologues may lead to tumorigenesis in HNPCC kindreds.  (+info)

Ecto-ATPase is an enzyme which belongs to the group of the E-NTPDases. Those enzymes are ectoenzymes, and that they participate in the metabolism of extracellular molecules. Ecto-ATPase participate in metabolism of nucleoside triphosphate and nucleoside diphosphate with higher affinity for the nucleoside triphosphate. The metabolism of extracellular molecules with the appropriate enzymes is one of the steps in purinergic signaling that mediates a variety of physiological and pathophysiological processes. Therefore it is considered that value of ecto-ATPase activity in human serum may be a potential factor in the diagnosis of diseases associated with purinergic signaling. Ecto-ATPase activity in the human serum was measured by Fiske-Subbarow method, and the average value of 13 healthy samples was 992.3±281.2 nmol/ml/h. Results showed that the most suitable sample volume for the measuring enzyme activity is 50 μL, incubation time on 37 °C is 60 min and that 100 μL 1.12 mol/L TCA is required ...

SecA is a central component of the general secretion system that is essential for bacterial growth and thus an ideal target for antimicrobial agents. A series of fluorescein analogues were first screened against the ATPase activity using the truncated unregulated SecA catalytic domain. Rose bengal (RB) and erythrosin B (EB) were found to be potent inhibitors SecA with IC50 values of 0.5 μM and 2 μM, respectively. RB and EB inhibit the catalytic SecA ATPase more effectively than the F1F0-proton ATPase. We used three assays to test the effect of these compounds on full-length SecA ATPase: in solution (intrinsic ATPase), in membrane preparation, and translocation ATPase. RB and EB show the following trend in terms of IC50 values: translocation ATPase,membrane ATPase,intrinsic ATPase. Very importantly, the potency of these fluorescein analogues in inhibiting the truncated SecA ATPase correlates with their ability to inhibit the biologically relevant protein translocation activity of SecA. The in ...
A cell surface-located nucleoside triphosphatase activity can be assayed in liver epithelial cultures in situ with the incubation of intact cells in a medium containing [γ-32P]adenosine triphosphate and correlated with the tumorigenicity of these cells in neonatal Wistar rats. The ectoenzyme activity of normal diploid cell lines is minimal, whereas a considerably high activity has been found in all tumorigenic cell lines tested. The optimum condition for the adenosinetriphosphatase activity is physiological with regard to osmolarity, ionic composition, pH, and substrate concentration in the medium. The enzyme is significantly stimulated by Ca2+, and its activation is controlled by Mg2+. Histochemical examinations indicate that glutaraldehyde-fixed cells of tumorigenic lines have Ca2+-stimulated adenosinetriphosphatase activity on the external surface. The isotopic assay of adenosine triphosphate hydrolysis by intact cells may provide a rapid method for screening oncogenesis in vitro of liver ...

The Hsp70 system interacts with extended peptide segments of proteins as well as partially folded proteins to prevent aggregation, remodel folding pathways, and regulate activity[7] When not interacting with a substrate peptide, Hsp70 is usually in an ATP bound state. Hsp70 by itself is characterized by a very weak ATPase activity, such that spontaneous hydrolysis will not occur for many minutes. As newly synthesized proteins emerge from the ribosomes, the substrate binding domain of Hsp70 recognizes sequences of hydrophobic amino acid residues, and interacts with them. This spontaneous interaction is reversible, and in the ATP bound state Hsp70 may relatively freely bind and release peptides. However, the presence of a peptide in the binding domain stimulates the ATPase activity of Hsp70, increasing its normally slow rate of ATP hydrolysis. When ATP is hydrolyzed to ADP the binding pocket of Hsp70 closes, tightly binding the now-trapped peptide chain. Further speeding ATP hydrolysis are the ...
Abstract: Within a daily period maximal activity of ATPases and content of 32P in Pliss lymphosarcoma tissue was found in the samples taken at 15 or 21 p.m. and 3 a.m. The radioactivity in the tumor was minimal between 9 and 12 a.m. and 18 or 24 p.m. The alterations in Mg2+-ATPase activity in their magnitude and circadian rhythm coincided completely with the daily variations in content of radiophosphorus. Activities of Na+, K+- and HCO(3-)-ATPases exhibited maximal values at 15 p.m. and, especially between 3 and 6 a.m., i.e. these alterations were of two-peak shape without the peak at 21 p.m ...
Spastin and katanin are ring-shaped hexameric AAA ATPases that sever microtubules, and thus crucially depend on a physical interaction with microtubules. For the first time, we report here the microtubule binding properties of spastin at the single-molecule level, and compare them to katanin. Microscopic fluorescence assays showed that human spastin bound to microtubules by ionic interactions, and diffused along microtubules with a diffusion coefficient comparable to katanin. The microscopic measurement of landing and dissociation rates demonstrated the ionic character of the interaction, which could be mapped to a patch of three lysine residues outside of the catalytic domain of human spastin. This motif is not conserved in Drosophila spastin or katanin, which also bound by non-catalytic parts of the protein. The binding affinities of spastin and katanin were nucleotide-sensitive, with the lowest affinities under ADP,, the highest under ATP-γS conditions. These changes correlated with the formation of

Involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). Component of SWI/SNF chromatin remodeling complexes that carry out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner. Required for maximal ATPase activity of SMARCA4/BRG1/BAF190A and for association of the SMARCA4/BRG1/BAF190A containing remodeling complex BAF with chromatin/nuclear matrix. Belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and is required for the proliferation of neural progenitors. During neural development a switch from a stem/progenitor to a postmitotic chromatin remodeling mechanism occurs as neurons exit the cell cycle and become committed to their adult state. The transition from proliferating neural stem/progenitor cells to postmitotic neurons requires a switch in subunit composition of the npBAF and nBAF complexes. As neural
Hsp90 couples ATP hydrolysis to large conformational changes essential for activation of client proteins. The structural transitions involve dimerization of the N-terminal domains and formation of closed states involving the N-terminal and middle domains. Here, we used Hsp90 mutants that modulate ATPase activity and biological function as probes to address the importance of conformational cycling for Hsp90 activity. We found no correlation between the speed of ATP turnover and the in vivo activity of Hsp90: some mutants with almost normal ATPase activity were lethal, and some mutants with lower or undetectable ATPase activity were viable. Our analysis showed that it is crucial for Hsp90 to attain and spend time in certain conformational states: a certain dwell time in open states is required for optimal processing of client proteins, whereas a prolonged population of closed states has negative effects. Thus, the timing of conformational transitions is crucial for Hsp90 function and not cycle ...
This work establishes Lis1 as a dynein regulatory protein and links its function to dynein enzymatic activity. The simplest interpretation of our data is that Lis1 acts specifically and directly on dynein. Although the increase in ATPase activity is modest at first glance, our determination that only one-third of the dynein molecules interacted with Lis1 suggests that there were two populations of motors present in the ATPase assay. The major population did not stably bind Lis1 and is not expected to have had any change in ATPase activity, whereas a smaller population binds Lis1, resulting in a boost in ATPase activity. In this scenario, the enzymatic activity of the dynein as a whole would have increased by only 40%, but the activity of Lis1-associated motors may have increased by ∼100%.. The finding that Lis1 can stimulate dynein in vitro supports our model that Lis1 has an activating influence on dynein in cells (Smith et al., 2000). In our previous work, we found that raising Lis1 ...
Adenosine triphosphate (ATP) is an important macro molecule that is the prime supplier of energy to run cell metabolism and to regulate several physiological processes in a cell. Despite its central role, the number of non-invasive methods to study ATP on a single cell level in real time are limited. ATPases use energy derived from ATP hydrolysis to maintain cell membrane potential by regulating ion gradients across the plasma membrane. It is generally believed that the Na+/K+-ATPase (NKA) which belongs to the P-type ATPase superfamily represent the main energy consumer among the ATPases. In this study, we set out to quantify ATP consumption by NKA on a single cell level in human embryonic kidney cells (HEK293a) using PercevalHR, a genetically encoded fluorescent biosensor that reports changes in the ATP:ADP during live cell imaging. We demonstrate that ATP hydrolysis by NKA is faster at physiological temperatures (35 -37°C) compared to room temperature. K+ free KREBS pre-treatment increased ...
The microtubule (MT)‐severing enzyme katanin triggers dynamic reorientation of cortical MT arrays that play crucial functions during plant cell morphogenesis, such as cell elongation, cell wall biosynthesis, and hormonal signaling. MT severing specifically occurs at crossover or branching nucleation sites in living Arabidopsis cells. This differs from the random severing observed along the entire length of single MTs in vitro and strongly suggests that a precise control mechanism must exist in vivo. However, how katanin senses and cleaves at MT crossover and branching nucleation sites in vivo has remained unknown. Here, we show that the katanin p80 subunit KTN80 confers precision to MT severing by specific targeting of the katanin p60 subunit KTN1 to MT cleavage sites and that KTN1 is required for oligomerization of functional KTN80-KTN1 complexes that catalyze severing. Moreover, our findings suggest that the katanin complex in Arabidopsis is composed of a hexamer of KTN1-KTN80 heterodimers ...
Implementing protein degradation is integral to enabling the function of many dynamical circuits, such as oscillators or feed-forward loops. We have been exploring the overexpression of AAA ATPases ClpXP to selectively target proteins with degradation tags. Initial experiments indicate that ClpXP, when overexpressed, can accelerate degradation of purified eGFP-ssrA (Fig. 1). We will further characterize this AAA ATPase family, as well as try to demonstrate its use through an incoherent feed-forward loop. We have not been able to replicate the results by adding purified ClpXP protein. However, we intend to express ClpXP off of plasmids or to create custom extract with ClpXP already overexpressed to enable rapid protein degradation. ...

The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of Na+/K+ -ATPases. Na+/K+ -ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The catalytic subunit of Na+/K+ -ATPase is encoded by multiple genes. This gene encodes an alpha 3 subunit. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012 ...
