Molecular dynamics studies of U1A-RNA complexes. (1/8682)

The U1A protein binds to a hairpin RNA and an internal-loop RNA with picomolar affinities. To probe the molecular basis of U1A binding, we performed state-of-the-art nanosecond molecular dynamics simulations on both complexes. The good agreement with experimental structures supports the protocols used in the simulations. We compare the dynamics, hydrogen-bonding occupancies, and interfacial flexibility of both complexes and also describe a rigid-body motion in the U1A-internal loop complex that is not observed in the U1A-hairpin simulation. We relate these observations to experimental mutational studies and highlight their significance in U1A binding affinity and specificity.  (+info)

Gangliosides of human kidney. (2/8682)

Five gangliosides isolated from human kidney have been characterized. The two main fractions were shown to be typical extraneural gangliosides in having lactose as their neutral carbohydrate moiety. Their structures were identified as: AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-8)AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer. The two main hexosamine-containing gangliosides are structurally related to human blood group substances of glycosphingolipid nature. The following structures are postulated: AcNeu(alpha2-3)Gal(beta1-4)GlcNAc(beta1-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-3)Gal(beta1-4)[Fuc(alpha1-3)]GlcNAc(beta1-3)Gal(beta1-4)Glc(beta1-1) Cer. The third hexosamine-containing ganglioside belongs to a different series of glycolipids and was shown to have the structure of a major ganglioside of human brain: AcNeu(alpha2-3)Gal(beta1-3)GalNAc(beta1-4)[AcNeu(alpha2-3)]Gal(beta1-4)Glc(beta1- 1)Cer. The fatty acid structure of different gangliosides was shown to resemble that of neutral glycolipids of human kidney with the nonhydroxy acids C16:0, C22:0, and C24:0 as major components.  (+info)

Carbon 13 NMR study of nonenzymatic reactions of pyridoxal 5'-phosphate with selected amino acids and of related reactions. (3/8682)

Carbon 13 nuclear magnetic resonance spectroscopy has been used to monitor the nonenzymatic reactions of pyridoxal 5'-phosphate with glycine, alanine, valine, serine, and with several other model compounds. Isotopically enriched amino acids were employed so that low concentrations could be utilized while still allowing relatively rapid acquisition of spectral data. The results for alanine and serine are particularly noteworthy in that alanine is deaminated to pyruvate and pyruvate is aminated to alanine, but contrary to the enzymatic reactions of various serine dehydratases wherein serine is converted to pyruvate, the nonenzymatic reaction utilizing serine results in hydroxypruvate rather than pyruvate formation. In the reverse reaction, hydroxypyruvate is aminated to serine but very inefficiently relative to the amination of pyruvate to alanine. The experimental results have been formulated into a proposed reaction mechanism for deamination of amino acids by pyridoxal-P.  (+info)

Voltage sensors in domains III and IV, but not I and II, are immobilized by Na+ channel fast inactivation. (4/8682)

Using site-directed fluorescent labeling, we examined conformational changes in the S4 segment of each domain of the human skeletal muscle sodium channel (hSkM1). The fluorescence signals from S4 segments in domains I and II follow activation and are unaffected as fast inactivation settles. In contrast, the fluorescence signals from S4 segments in domains III and IV show kinetic components during activation and deactivation that correlate with fast inactivation and charge immobilization. These results indicate that in hSkM1, the S4 segments in domains III and IV are responsible for voltage-sensitive conformational changes linked to fast inactivation and are immobilized by fast inactivation, while the S4 segments in domains I and II are unaffected by fast inactivation.  (+info)

Quantitative study of polymer conformation and dynamics by single-particle tracking. (5/8682)

We present a new method for analyzing the dynamics of conformational fluctuations of individual flexible polymer molecules. In single-particle tracking (SPT), one end of the polymer molecule is tethered to an immobile substratum. A microsphere attached to the other end serves as an optical marker. The conformational fluctuations of the polymer molecule can be measured by optical microscopy via the motion of the microsphere. The bead-and-spring theory for polymer dynamics is further developed to account for the microsphere, and together the measurement and the theory yield quantitative information about molecular conformations and dynamics under nonperturbing conditions. Applying the method to measurements carried out on DNA molecules provides information complementary to recent studies of single DNA molecules under extensional force. Combining high precision measurements with the theoretical analysis presented here creates a powerful tool for studying conformational dynamics of biological and synthetic macromolecules at the single-molecule level.  (+info)

The structure of human parathyroid hormone-related protein(1-34) in near-physiological solution. (6/8682)

Parathyroid hormone-related protein plays a major role in the pathogenesis of humoral hypercalcemia of malignancy. Under normal physiological conditions, parathyroid hormone-related protein is produced in a wide variety of tissues and acts in an autocrine or paracrine fashion. Parathyroid hormone-related protein and parathyroid hormone bind to and activate the same G-protein-coupled receptor. Here we present the structure of the biologically active NH2-terminal domain of human parathyroid hormone-related protein(1-34) in near-physiological solution in the absence of crowding reagents as determined by two-dimensional proton magnetic resonance spectroscopy. An improved strategy for structure calculation revealed the presence of two helices, His-5-Leu-8 and Gln-16-Leu-27, connected by a flexible linker. The parathyroid hormone-related protein(1-34) structure and the structure of human parathyroid hormone(1-37) as well as human parathyroid hormone(1-34) are highly similar, except for the well defined turn, His-14-Ser-17, present in parathyroid hormone. Thus, the similarity of the binding affinities of parathyroid hormone and parathyroid hormone-related protein to their common receptor may be based on their structural similarity.  (+info)

Apolipoprotein A-I charge and conformation regulate the clearance of reconstituted high density lipoprotein in vivo. (7/8682)

While low apolipoprotein A-I (apoA-I) levels are primarily associated with increased high density lipoprotein (HDL) fractional catabolic rate (FCR), the factors that regulate the clearance of HDL from the plasma are unclear. In this study, the effect of lipid composition of reconstituted HDL particles (LpA-I) on their rate of clearance from rabbit plasma has been investigated. Sonicated LpA-I containing 1 to 2 molecules of purified human apoA-I and 5 to 120 molecules of palmitoyl-oleoyl phosphatidylcholine (POPC) exhibit similar charge and plasma FCR to that for lipid free apoA-I, 2.8 pools/day. Inclusion of 1 molecule of apoA-II to an LpA-I complex increases the FCR to 3.5 pools/day, a value similar to that observed for exchanged-labeled HDL3. In contrast, addition of 40 molecules of triglyceride, diglyceride, or cholesteryl ester to a sonicated LpA-I containing 120 moles of POPC and 2 molecules of apoA-I increases the negative charge of the particle and reduces the FCR to 1.8 pools/day. Discoidal LpA-I are the most positively charged lipoprotein particles and also have the fastest clearance rates, 4.5 pools/day. Immunochemical characterization of the different LpA-I particles shows that the exposure of an epitope at residues 98 to 121 of the apoA-I molecule is associated with an increased negative particle charge and a slower clearance from the plasma. We conclude that the charge and conformation of apoA-I are sensitive to the lipid composition of LpA-I and play a central role in regulating the clearance of these lipoproteins from plasma. conformation regulate the clearance of reconstituted high density lipoprotein in vivo.  (+info)

A scan conversion process is performed on a polygon using a single pass technique. The pixels which comprise the edges and vertices of the polygon are first determined from the vertices which define the polygon. The alpha channel comprises either a sub-pixel mask associated with each pixel which indicates the amount and sub-pixel regions of coverage or a single value indicative of the percentage of coverage of a pixel. Furthermore, a z value indicative of the depth of each pixel is maintained. The pixels between the edge pixels of the polygon are then turned on, thereby filling the polygon. The pixels which comprise the polygon are then composited with the background pixels on a per pixel basis. The depth value of each pixel of the polygon (the z value) is used to determine the compositing equations to be used to composite each pixel of the polygon to the background. The compositing equations update the color of the pixel, the z buffer value of the background pixel and the sub-pixel mask to reflect the

When the first of these half-way boundaries are crossed, the corresponding polygon is chosen, the half-way point defined, and also a trace, a part of the polygon outline, is selected as follows: The start point and the half-way point define a direction. From the start point inside the angle range 30-60 degrees left one looks for a polygon point to act as trace endpoint (full blue circle). If there are several, one chooses the "best" as endpoint, which usually means the point nearest to the 45 degrees direction. If there is no point within that angle range but a polygon face, then a candidate endpoint (open circle) is placed on it at 45 degrees. Then repeat for the angle range to the right. There is a continuous polygon trace between two endpoints (blue), any segment of it connected to an endpoint is an endpoint segment. There may be intermediate points and intermediate segments (violet). Possibly this trace should be highlighted at that point in the GUI. ...

Patent US3816726 - Computer graphics clipping system for polygons - Google PatentsPatent US3816726 - Computer graphics clipping system for polygons - Google Patents
A system is disclosed for clipping three-dimensional polygons for use in a computer-graphics display. The system removes from each polygon all parts that lie outside an arbitrary, plane-faced, convex polyhedron, e.g. a truncated pyramid defining a viewing volume. The polygon is defined by data representing a group of vertices and is clipped separately in its entirety against each clipping plane (of the polyhedron). In a multiple-stage structure as disclosed, each stage clips the polygon against a single plane and requires storage for only two vertex values. A time-sharing embodiment of the system is also disclosed. The disclosed system also incorporates the use of a perspective transformation matrix which provides for arbitrary field-of-view angles and depth-of-field distances while utilizing simple, fixed clipping planes.

The term polygon is one that people encounter very early on and thus, in my opinion, should have an entry that gives basic information about polygons that are both mathematically precise and accessible to the general population.. Also, I am pretty sure that this entry went up for adoption due to the fact that terms such as interior angle and exterior angle are difficult to define in a mathematically precise way. Nevertheless, these terms (along with angle sum) are commonly used and should appear somewhere in PM..

Molecular models for the smectic A-smectic C phase transition in a system of biaxial molecules - StrathprintsMolecular models for the smectic A-smectic C phase transition in a system of biaxial molecules - Strathprints
A molecular theory of the smectic A-smectic C transition in a system of biaxial molecules is developed in the mean-field approximation. The influence of molecular biaxiality on the transition is considered in detail and it is demonstrated how the biaxial order parameters are induced by the tilt. It is shown that the ordering of biaxial molecules of low symmetry in the smectic C phase is generally described by ten independent orientational order parameters, and there exist three different tilt angles which specify the tilt of three ordering tensors. The order parameters are calculated numerically as functions of temperature for two models of biaxial molecules: molecules with two principal axes and molecules with a pair of off-center transverse dipoles. A substantial difference between the three tilt angles is found, which makes impossible a strict definition of a unique director in the smectic C phase. It is also shown that biaxial interactions may lead to an anomalously weak layer contraction in ...

Smoothing with less polygons - Blender.orgSmoothing with less polygons - Blender.org
Hi! Im new to Blender, I used to use 3dsmax, and I decided to give Blender a chance. My question is: is there any way to smooth a mesh without having to deal with thousands of polygons? In 3dsmax I would create a sphere with 32 segments and it would render 960 polys, really quickly. In Blender, the render looks smooth only after applying subsurf/catmull-clark with 3 subdiv, which renders 49600 polys! and given that I do this just for fun, and my pc is awful, it results in a considerable difference of time between 3dsmax and Blender... Is there anything I could do ...

In modern biology, all life, with the exception of some viruses, uses DNA as its genetic storage mechanism. According to the "RNA-world" hypothesis, RNA appeared on Earth first, serving as both the genetic-storage material and the functional molecules for catalyzing chemical reactions, then DNA and proteins evolved much later. Unlike DNA, RNA can adopt many different molecular conformations and so it is functionally interactive on the molecular level. In the research paper, two professors of chemistry, Christine Keating and Philip Bevilacqua, along with two graduate students, Christopher Strulson and Rosalynn Molden, probe one of the nagging mysteries of the RNA-world hypothesis.. "A missing piece of the RNA-world puzzle is compartmentalization," Bevilacqua said. "Its not enough to have the necessary molecules that make up RNA floating around; they need to be compartmentalized and they need to stay together without diffusing away. This packaging needs to happen in a small-enough space - ...

Polygon - Simple English Wikipedia, the free encyclopediaPolygon - Simple English Wikipedia, the free encyclopedia
A polygon is a closed two-dimensional shape. It is a simple curve that is made up of straight line segments. It usually has three sides/corners or more. It could also be referred to as A closed plane figure bound by three or more straight line segments. It has a number of edges. These edges are connected by lines. A square is a polygon because it has four sides. The smallest possible polygon in a Euclidean geometry or "flat geometry" is the triangle, but on a sphere, there can be a digon and a henagon. If the edges (lines of the polygon) do not intersect (cross each other), the polygon is called simple, otherwise it is complex. In computer graphics, polygons (especially triangles) are often used to make graphics. ...

Photo-induced phase transitions are characterized by the transformation from phase A to phase B through the absorption of photons. We have investigated the mechanism of the photo-induced phase transitions of four different ternary systems CiE4/alkane (i) with n = 8, 10, 12, 14; cyclohexane/H2O. We were interested in understanding the effect of chain length increase on the dynamics of transformation from the microemulsion phase to the liquid crystal phase. Applying light pump (pulse)/x-ray probe (pulse) techniques, we could demonstrate that entropy and diffusion control are the driving forces for the kind of phase transition investigated.

Abstract: A new isolated-pentagon-rule (IPR) C100(417)Cl28 has been captured, but its formation mechanism is still unclear. Herein we have used density functional theory (DFT) to study the possible reaction pathways, including Stone-Wales (SW) transformation, direct chlorination, and skeletal transformation for C100(417). The calculated results show that the major source of C100(417) is the skeletal transformation of C102(603), including chloride formation, C2 elimination, and SW transformation. The results satisfactorily explained the experimental observations, and provide useful guidance for the synthesis of fullerene chlorides..

The present research focuses on the vibrational simulation of the biological systems, including the harmonic-level normal modes analysis and the anharmonic-level vibrational self-consistent field (VSCF) calculation. Normal modes analysis was performed on a large biomolecule--ricin-A-chain (RTA)--in both apo- (no substrate) and holo- (adenosine monophosphate (AMP)-bound) state. It revealed that the shearing motion was shared by both apo- and holo-RTAs, whereas the breathing motion, as well as the upward hinge and the α-G bending characteristic motions, was dampened by substrate binding. We hypothesize that the breathing, α-G bending and upward hinging motions play an important role in substrate binding as these motions facilitate the entry of the substrate and provide space for the substrate realignment that is necessary for the depurination. The VSCF calculations, which were typically restricted to small systems, were performed in the present research on a moderate biomolecule--the VA-class ...

Microstructure and Phase Behavior in Colloids and Liquid Crystals by Matthew Alan Lohr"Microstructure and Phase Behavior in Colloids and Liquid Crystals" by Matthew Alan Lohr
This thesis describes our investigation of microstructure and phase behavior in colloids and liquid crystals. The first set of experiments explores the phase behavior of helical packings of thermoresponsive microspheres inside glass capillaries as a function of volume fraction. Stable helical packings are observed with long-range orientational order. Some of these packings evolve abruptly to disordered states as the volume fraction is reduced. We quantify these transitions using correlation functions and susceptibilities of an orientational order parameter. The emergence of coexisting metastable packings, as well as coexisting ordered and disordered states, is also observed. These findings support the notion of phase-transition-like behavior in quasi-one-dimensional systems. The second set of experiments investigates cross-over behavior from glasses with attractive interactions to sparse gel-like states. In particular, the vibrational modes of quasi-two-dimensional disordered colloidal packings of hard

Dihedral angle - WikipediaDihedral angle - Wikipedia
In chemistry, a torsion angle is defined as a particular example of a dihedral angle, describing the geometric relation of two parts of a molecule joined by a chemical bond.[4][5] Every set of three not-colinear atoms of a molecule defines a plane. When two such planes intersect (i.e., a set of four consecutively-bonded atoms), the angle between them is a dihedral angle. Dihedral angles are used to specify the molecular conformation.[6] Stereochemical arrangements corresponding to angles between 0° and ±90° are called syn (s), those corresponding to angles between ±90° and 180° anti (a). Similarly, arrangements corresponding to angles between 30° and 150° or between −30° and −150° are called clinal (c) and those between 0° and ±30° or ±150° and 180° are called periplanar (p). The two types of terms can be combined so as to define four ranges of angle; 0° to ±30° synperiplanar (sp); 30° to 90° and −30° to −90° synclinal (sc); 90° to 150° and −90° to −150° ...

Description:[email protected] is a research project that uses Internet-connected computers to solve challenging large-scale optimization problems. The goal of optimization is to find a minimum (or maximum) for a given function. This topic is perfectly explained in the Internet. See for example excellent explanation by Arnold Newumaier. Many practical problems are reduced to the global optimization problems. At the moment this project runs an application that is aimed at solving molecular conformation problem. This is a very challenging global optimization problem consisting in finding the atomic cluster structure that has the minimal possible potential energy. Such structures plays an important role in understanding the nature of different materials, chemical reactions and other fields ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. This paper presents a motion control algorithm for a planar mobile observer such as, e.g., a mobile robot equipped with an omni-directional camera. We propose a nonsmooth gradient algorithm for the problem of maximizing the area of the region visible to the observer in a simple nonconvex polygon. First, we show that the visible area is almost everywhere a locally Lipschitz function of the observer location. Second, we provide a novel version of LaSalle Invariance Principle for discontinuous vector elds and Lyapunov functions with a nite number of discontinuities. Finally, we establish the asymptotic convergence properties of the nonsmooth gradient algorithm and we illustrate numerically its performance. 1. Introduction. Consider

APS -APS March Meeting 2012 - Event - Experiments on ordering transitions in mechanically stable structures of granular rodsAPS -APS March Meeting 2012 - Event - Experiments on ordering transitions in mechanically stable structures of granular rods
We investigated the evolution of granular rods from mechanically stable disordered to crystalline states in response to vibrations. We obtained positions and orientations of the rods in three dimensions using micro-focus X-ray Computed Tomography. Above a critical aspect ratio, we find that rods align vertically in layers with hexagonal order within a layer, independent of the shape of the container and details of the form of vibration. We also quantitatively study the evolution of local and global ordering using density pair correlation function $g(r)$ and orientational order parameter $q_{6}$ as a function of aspect ratio. As the system compacts, local structures emerge and grow, their size and orientation being dependent on volume fraction. Although the initial nucleation of order occurs along the boundaries, we show that the geometry of boundaries have little overall effect on the observed ordering transition. Finally we show that configuration entropy arguments do not play a significant ...

Questions about Conformations and Energy ProfilesQuestions about Conformations and Energy Profiles
Another example of the initial conformer affecting systematic results can be found by inspecting an 8 member carbon chain: "C1-C2-C3-C4-C5-C6-C7-C8". For illustrative purposes consider the central "C4-C5" bond as we rotate it 360 degrees; from -180 to 180 degrees. If one starts in the all trans conformation, we find that as we rotate the "C4-C5" bond the final conformation of 360 degrees is identical to the initial at 0 degrees. However, if the initial conformation had a number of kinks in it, we might discover that at the 120 degree mark, the C1 and C8 ran into each other. To relieve this steric problem the other dihedral angles, will relax, likely changing by more than 100 degrees and falling into new energy wells. As we continue the coordinate driving of the central C4-C5 angle to trans (180), we might find that the final conformation is not the same as the initial conformation because these other dihedrals have changed ...

Building an IcosahedronBuilding an Icosahedron
This project will allow students to be hands-on in building a platonic solid. It is a good project to do after solids are covered in your class. Your students will already know about regular polygons and they may even be able to derive on their own that there are only 5 platonic solids. Have them start with equilateral triangles and see if they can figure out how many objects they could possibly build and then move on to squares, pentagons, and then hexagons, etc. It is easiest to have the students try and figure out many how faces they could possibly have come together at one vertex to build a solid. Working with angles they should derive that it is impossible to build a solid with n-sided polygons where .. Applicable ...
Scratch Programming: Ant Poly - a Generalized Polygon ScriptScratch Programming: Ant Poly - a Generalized Polygon Script
Many years ago, when classroom computers first became available, we created Computer Labs at each of the three middle schools in our district. Every student cycled through a lab, for one period a day, for a semester. We wrote our own curriculum and two-thirds of the class time was spent teaching the kids Logo, the first kid-friendly programming language to originate at MIT. Logo, like Scratch, makes it very easy to turn the normally static study of geometry into a very dynamic experience for the kids. ...
Re: Polygon Filling algorithm in PerlRe: Polygon Filling algorithm in Perl
totally random thought... I notice you defined all of your y coords based on the height .. but you used subtraction, so youre still making an assumption about the minimum height. Any time you can define some constraint on a value given another value, you should consider doing so in your code. That way if someone says "Hey this is cool, but its a little big so ill change the size to 50x60" your code can deal with the change flawlessly... ...

The benefit of this circle / polygon combo is that it draws your eye in. The downside is that it is not clear where the image belongs in the overall narrative. Is it an example for the Introduction? Or maybe the Results? The corner of the polygon almost forms an arrow pointing down to the Results. This might be a cue for the reader, but its so subtle that its hard to tell if that was deliberate or not. The central circle could even be part of the Methods, although the position doesnt suggest that as strongly as the other two ...

  • We have previously shown that the conformation of nascent polypeptide chains in transit through the ribosome-translocon complex can be probed by measuring the number of residues required to span the distance between the ribosomal P-site and the lumenally disposed active site of the oligosaccharyl transferase enzyme (J. Biol. (biomedcentral.com)
  • Chem 271: 6241-6244).Using this approach, we now show that model segments composed of residues with strong helix-forming properties in water (Ala, Leu) have a more compact conformation in the ribosome-translocon channel than model segments composed of residues with weak helix-forming potential (Val, Pro). (biomedcentral.com)
  • L 17 V, A 17 V, V 18 , P 18 ) in locations that are either within the ribosome or the translocon in the truncated nascent chain we find that d P-O values tend to fall near either 65 or 70 residues, and we equate these two values with extended and helical conformations of the model stretches, respectively.
