Reviewer #3: This study compared the EFMO method with ONIOM method as for the reaction free energy barrier for the Chorismate Mutase. In general, the results are more consistent than that of the ONIOM. This review agrees that the current manuscript is publishable, and expect the authors to explain the possible reasons for: (1) the calculated free energy barrier is much higher than that of the experimentally measured enthalpy change? (2) The authors claimed that the MP2-geometry optimization make it 3.5 kcal/mol lower for the free energy barrier than that of the ONIOM method, however, the listed data of free energy barrier in Table2 is close to each other at the same calculation level. (3) The portability to other enzyme system of EFMO method ...

TY - JOUR. T1 - Nuclease resistance of an extraordinarily thermostable mini-hairpin DNA fragment, d(GCGAAGC) and its application to in vitro protein synthesis. AU - Yoshizawa, Satoko. AU - Ueda, Takuya. AU - Ishido, Yoshiharu. AU - Miura, Kin ichiro. AU - Watanabe, Kimitsuna. AU - Hirao, Ichiro. PY - 1994/6/25. Y1 - 1994/6/25. N2 - The nuclease resistance of a short, thermostable minihairpin, d(GCGAAGC), and other related hairpins was examined. Hairpins possessing a purine-rich (GAA) or (GAAA) loop appeared to be more resistant against nucleases than those with a pyrimidine-rich loop or single-stranded oligomers. Among 8 kinds of oligodeoxyribonucleotides examined, the fragment most resistant against nucleases was a hairpin with the sequence of d(CGCGAAGCG). This hairpin was then utilized for the stabilization of mRNA in an in vitro translation system; the 3′-terminal region of an mRNA was hybridized with an oligodeoxyribonucleotide including the sequence complementary to the 3′-terminus of ...

Abstract: Computational methods have been widely used to characterize the catalytic mechanisms of several chemical systems namely enzymes. However, enzymes are studied using big chemical systems containing several thousands of atoms generating huge amounts of data that are hard to manipulate and analyze efficiently. Therefore, we developed molUP that is a user-friendly plugin for VMD to handle QM and ONIOM calculations performed using Gaussian software. MolUP allows loading output files from Gaussian calculations and performs analysis concerning the structure of the chemical system as well as their energies and vibrational frequencies. Furthermore, molUP provides a graphical interface to manipulate the length of atomic bonds and the amplitude of angles and dihedral angles. Users can also easily choose which atoms belong to each ONIOM layer and the atoms that are free to move during a geometry optimization. At the end, molUP is capable of saving the new structure as a new Gaussian input file, ...

Popsicle sticks can be a useful tool for creating a visual display of DNA in a double-helix form. The double-helix structure takes the shape of a ladder that winds around itself repeatedly.

Recognition and biochemical processing of DNA requires that proteins and other ligands are able to distinguish their DNA binding sites from other parts of the molecule. In addition to the direct recognition elements embedded in the linear sequence of bases (i.e. hydrogen bonding sites), these molecu …

Yes, Bob, I just saw those comments and deleted them. Ill have to go mark them as spam. The château de Blois has a spiral staircase, but it isnt a double-helix staircase like the one at Chambord. The first time I was at Chambord was in wintertime about 45 years ago. There wasnt much in the way of furniture in the château back then, but big fires were roaring in all the fireplaces and it was very atmospheric. I always find it easy to say something is beautiful but Im not so fast to declare something unbeautiful. Eye of the beholder, and all that.. Delete ...

Novel oligomers are disclosed which have enhanced ability with respect to forming duplexes or triplexes compared with oligomers containing only conventional bases. The oligomers contain the base analog 5-propynyluracil, 5-propynylcytosine or related analogs. The oligomers of the invention are capable of (i) forming triplexes with various target sequences such as virus or oncogene sequences by coupling into the major groove of a target DNA duplex at physiological pH or (ii) forming duplexes by binding to single-stranded DNA or to RNA encoded by target genes. The oligomers of the invention may be constructed to have any desired sequence, provided the sequence normally includes one or more bases that is replaced with the analogs of the invention. Compositions of the invention can be used for diagnostic purposes in order to detect viruses or disease conditions.

As we will see in the rest of this volume, several of these tenets [of the Modern Synthesis] are being challenged as either a inaccurate or incomplete. It is important however, to understand the kind of challenge being posted here, in order to avoid wasting time on unproductive discussions that miss the point of an extended evolutionary synthesis. Perhaps a parallel with another branch of biology will be helpful. After Watson and Crick discovered the double-helix structure of DNA, and the molecular revolution got started in earnest, one of the first principles to emerge from the new discipline was the unfortunately named central dogma of molecular biology. The dogma (a word that arguably should never be used in science) stated that the flow of information in biological systems is always one-way, from DNA to RNA proteins. Later on, however, it was discovered that the DNA > RNA flow can be reversed by the appropriately named process of reverse transcription, which takes place in a variety of ...

By Yannis Grammatikakis. Monday, April 20, 2015. Ever since the discovery of the double-helix structure of DNA, scientists have sought ways to edit the genome.

American scientists have engineered the first life forms that carry artificial DNA - DNA that can also be passed on to their offspring in a move that shakes up our understanding of life itself.

In this work the photophysics of four bichromophoric units was studied by means of static and time resolved spectroscopy, with the aim of disentangling the contribution of steric and electronic factors in regulating the efficiency of electronic energy transfer (EET). The newly synthesized dyads share the same acceptor moiety, a substituted BODIPY chromophore, and differ either in the donor or in the molecular bridge connecting the two units. The use of different linkers allows for tuning the conformational flexibility of the dyad, while changing the donor has an influence on the electronic coupling and spectral overlap between the two chromophores. The efficiency of energy transfer is extremely high in all the four dyads and can be modelled within the frame of the Förster equation. In the special case of a dimeric donor, a theoretical analysis was performed to further support the experimental findings. Geometry optimization at DFT level indicated that different conformations with similar energy ...

Distance Geometry Optimization and Applications. A distance geometry problem is to find the coordinates for a set of points in a given metric space given the distances for the pairs of points. The distances can be dense (given for all pairs of points) or sparse (given only for a subset of all pairs of points). They can be provided with exact values or with small errors. They may also be given with a set of ranges (lower and upper bounds). In any case, the points need to be determined to satisfy all the given distance constraints. The distance geometry problem has many important applications such as protein structure determination in biology, sensor network localization in communication, and multidimensional scaling in statistical classification. The problem can be formulated as a nonlinear system of equations or a nonlinear least-squares problem, but it is computationally intractable in general. On the other hand, in practice, many problem instances have tens of thousands of points, and an ...

TY - JOUR. T1 - Molecular structure of the octatetranyl anion, C8H-. T2 - A computational study. AU - Pichierri, Fabio. PY - 2008/8/21. Y1 - 2008/8/21. N2 - The equilibrium molecular structure of the octatetranyl anion, C 8H-, which has been recently detected in two astronomical environments, is investigated with the aid of both ab initio post-Hartree-Fock and density functional theory (DFT) calculations. The model chemistry adopted in this study was selected after a series of benchmark calculations performed on molecular acetylene for which accurate gas-phase structural data are available. Geometry optimizations performed at the CCSD/6-311+G(2d,p), QCISD/6-311+G(2d,p), and MP4(SDQ)/6-311+G(2d,p) levels of theory yield for C8H - an interesting polyyne-type structure that defies the chemical formula displaying a simple alternation of triple and single carbon-carbon bonds, [:C≡C-C≡C-C≡C-C≡CH]1-. In the optimized geometry of C8H-, as one proceeds from the naked carbon atom on one side of ...

An efficient formulation of the fragment molecular orbital method is introduced based on dividing the system into frozen and polarizable domains. The former is computed once taking into account the many-body polarization of the whole system, while the latter is recalculated for each step of a geometry optimization. We performed ligand docking and calibrated the method on the complexes of the Trp−cage miniprotein construct (PDB: 1L2Y) with neutral and charged ligands and applied it to optimize a partially solvated structure of prostaglandin H(2) synthase-1 in complex with the reversible competitive inhibitor ibuprofen (PDB: 1EQG) containing 19471 atoms at the B3LYP-D/6-31G* and RHF/STO-3G levels of theory for the polarizable and frozen domains, respectively. The optimization took 32 h on six dual CPU quad-core 2.83 GHz Xeon nodes. Our method requires no fitted parameters and allows optimizations of large systems based solely on quantum mechanics ...

The crystal and molecular structures of [In(r,5-P2C3But3)] are reported. He I and He II photoelectron (PE) spectra of [InCn-PjQBui)] and of [In(n5-PjC3Buj)] are assigned by comparison with related systems and with the aid of density functional calculations of the ionisation energies (IE). In both cases the first PE band comprises ionisation from the ring n levels together with an ionisation from a Pa orbital. The second band is due to ionisation from an In-ring antibonding orbital with In s character. Other Per ionisation bands lie at higher IE. Substitution of CBu by P within the five membered aromatic ring increases the IE of related bands. Geometry optimisation of the parent complexes [In(n5-P3C2H2)] and [In(n5-P2C3H3)] gave structural parameters in good agreement with the X-ray data. Attempts to find an energy minimum corresponding to n-coordination were unsuccessful, the structures reverting to the n5-coordination mode. Bonding of the ring is principally due to overlap of the two upper ...

In this investigation, the interaction of C20 and Si2H2 molecules was explored in the M06-2X/6-311++G(d,p) level of theory in gas solution phases. The obtained interaction energy values with standard method were corrected by basis set superposition error (BSSE) during the geometry optimization for all molecules at the same level of theory. Also, the bonding interaction between the C20 and Si2H2 fragments was analyzed by means of the energy decomposition analysis (EDA). The results obtained from these calculations reveal interaction between C20 and Si2H2 increases in the presence of more polar solvents. There are good correlations between these parameters and dielectric constants of solvents. The wavenumbers of IR-active, symmetric and asymmetric stretching vibrations of Si-H groups and 29Si NMR chemical shift values in different solvents were correlated with the Kirkwood-Bauer-Magat equation (KBM).

What is DNA?. DNA (deoxyribonucleic acid) is a chemical found inside living things, such as plant, animals and bacteria. Living things are made of cells where cells make up tissues and organs. The DNA chemical occurs as molecules inside each cell. Inside the cell, DNA is packaged into chromosomes. Each chromosome is basically a very long DNA molecule that is tightly compacted. Each species has a different number of chromosomes, with humans having 23 pairs of chromosomes. The totality of DNA packaged into chromosomes is the genome. DNA itself is a very long molecule, made up of two-strands wound around each other, called a double-helix. Each strand is made up of a long string of units joined together. There are four different units in DNA, labelled with the letters A, T, G, and C, which stand for the identifying bases for each unit, adenine, thymine, guanine and cytosine. Previously, it was commonly thought by geneticists that all the information required to build an organism is stored in DNA, ...

DNA replicates when a double-helix molecule splits down the middle in the presence of component amino acids. Those amino acids take their place on each half of the molecule, creating two new double helices where once there was one. This happens in normal, microscopic, cell growth. In the macroscopic biblical world, it happened at least three times: twice when loaves and fish were broken and distributed among seven thousand men plus wives and children (possibly more than twenty thousand people!), once when tissue3 was taken from Adams side and built up4 - minus the Y-chromosomes - into a woman.5 Eve was a clone of Adam. The appropriate building blocks were produced (summoned? Created ex nihilo? Not important6 ), took their place along the incompleted edges, and the final product emerged.. And the spirit? God didnt breathe a separate spirit into Eves nostrils as he did Adams, so it must be assumed that the spirit-in-potential was present with, and linked to, Adams cells (I wont say in ...

The PCILO quantum-chemical method with geometry optimization has been used to study rotation barriers of methyl groups in N-methylacetamide and N,N-dimethylacetamide. In all the cases studied, the eclipsed conformation have been found to be the most stable. Cis form of N-methylacetamide is less stable than the corresponding trans form by 2.0 kJ mol-1. Moreover, the PCILO method has been used to study linear n-mers (n = 4) of N-methylacetamide. On going from the dimer to tri- and tetramers, the hydrogen-bond energies have been found non-additive, and positive cooperativity has been observed. Finally, hydrogen-bond complexes have been studied which were formed by C=O groups of N-methylacetamide and N,N-dimethylacetamide with water, methanol or phenol as proton-donors. The said proton-donors have been found to act as breakers of inter-peptide hydrogen bonds N-H...O=C. The hydrogen bonds formed by methanol are somewhat stronger than those formed by water. In accordance with experiment, the strongest ...

Addicoat and Mehta1 have made a modification of the Kick algorithm. Recall, that the Kick method (discussed in this previous blog post) takes a collection of atom coordinates and applies a random kick to each atom. This creates a new initial configuration and a geometry optimization is performed starting form this configuration. If hundreds of such configurations are chosen, one hopes to locate most if not all reasonable structures. The new variation is to create fragments in which the atoms are held fixed. Then the kick is applied to the fragment as a whole.. Among the examples demonstrated in the paper, only one is of an organic species. They examined the structure of the Gly-Trp peptide associated with two water molecules. They used two conformations of the Gly-Trp dipeptide. The kick was supplied to one of these conformers and to the two water molecules. They ended up locating 22 structures with the first conformer and 46 with the second, spanning a range of about 0.5 eV. It must be ...

Dimers of lithium formamidinate, CH(NH)2Li, and halogenated formamidines, HN=CHNHX, (X=Cl, Br, or I) are used as model systems to investigate simultaneous N-X···N and N-Li···N interactions, in tandem with orthogonal Li···X interactions. Geometry optimizations and energy calculations for the dimers are examined with the MP2 method and the M06-2X hybrid functional and the aug-cc-pVTZ basis set (the aug-cc-pVTZ-PP basis set is used for the iodine atom). Both methods predict the formation of a planar structure of C2v symmetry, regardless of the identity of the halogen atom. In this structure, the identities of the constituent monomers are essentially lost. Accordingly, the N-X···N interactions emerge as a rather symmetric quasi-linear N···X···N, where the covalent N-X bond in the halogenated formamidine is replaced by a partly covalent N···X interaction. Formation of the C2v structure is also driven by a fairly linear N···Li···N interaction parallel to the N···X···N

Two novel complexes for Zn2+ and VO2+ ions, were prepared from tridentate dibasic chelating Schiff base ligand. 1-((3,5-di-tert-butyl-2-hydroxybenzylidene)amino)naphthalen-2-ol-5‑sodium sulfonate (DSHN), was the ligand used in this study. Alternative spectral tools were applied to elucidate structural composition of new compounds. Also, geometry optimization for all synthesizes was conducted by Gaussian09 program via DFT method, to obtain optimal structures and essential parameters. Moreover, the biochemical behavior for all synthesizes, was explored based on tested reactivity against various microbial strains and cancer cells (HCT-116, MCF-7, and HepG-2). The two complexes exhibited interestingly anti-proliferative potential against human cancer cell lines. The antioxidant behavior of the two complexes was studied by DPPH and SOD assays. Particularly, Zn(II) and VO(II) complexes presented more enhanced antimicrobial and anticancer features compared to the free ligand (DSHN), with superiority ...

Molecular Modeling for the Design of PABA/NO. The Meisenheimer complexes formed by GSH and PABA/NO for GSTπ and GSTα were built based on those for JS-K (Shami et al., 2003). The models were subject to geometry optimization and docked into the active sites of GSTπ (Prade et al., 1997) and GSTα (Sinning et al., 1993), respectively. Model building was carried out with computer graphics program O (Jones and Kjeldgaard, 1997) and energy minimization with Crystallography & NMR System software (Brünger et al., 1998). Illustrations were generated with software packages Grasp (Nicholls et al., 1991), Molscript (Kraulis, 1991), and Raster3D (Merritt and Bacon, 1997)..

Both phosphoryl and sulfuryl transfers are ubiquitous in biology, being involved in a wide range of processes, ranging from cell division to apoptosis. Additionally, it is becoming increasingly clear that enzymes that can catalyze phosphoryl transfer can often cross-catalyze sulfuryl transfer (and vice versa). However, while there have been extensive experimental and theoretical studies performed on phosphoryl transfer, the body of available research on sulfuryl transfer is comparatively much smaller. The present work presents a direct theoretical comparison of p-nitrophenyl phosphate and sulfate monoester hydrolysis, both of which are considered prototype systems for probing phosphoryl and sulfuryl transfer, respectively. Specifically, free energy surfaces have been generated using density functional theory, by initial geometry optimization in PCM using the 6-31+G* basis set and the B3LYP density functional, followed by single-point calculations using the larger 6-311+G** basis set and the ...

The microscope, which will be able to visualize the structure of proteins and DNA at an atom-by-atom scale, will be installed in the Crocker Science Center, currently under construction on Presidents Circle. The microscopes resolution is fine enough to see details such as the double-helix and ladder structure of DNA, said biochemistry professor Wesley Sundquist.. Biochemistry and molecular biology take place on the atomic scale, enzymes work on the atomic scale, drugs bind on the atomic scale - so thats information thats really critical for understanding how biological processes work, Sundquist said..

Now, of course, the original planners were not about to lose the territory -- did you think they were going to give up so easily? Of course they exist in a different time sector than you. So, the new owners came and worked in their laboratory, and created workers, created versions of humans with a different DNA, the two-stranded double-helix DNA. They took the original DNA of the human species, and they disassembled it. Yes, isnt that clever? They disassembled the original DNA. And they left it, of course, within the human cell. They simply split it apart.. Within the human cells are what we call light encoded filaments, fine gossamer threads of energy that carry information. And when those gossamer threads are working together, like a cable, fiber optics as it would be, they form the helix, the helix of your DNA. Of course when you were rearranged, you were left with two helix, the double helix, half lit, In other words, anything that was unnecessary, that would keep you informed, was ...

Can you recall anything within Darwins dogma that could explain, using genetics, how our population has suddenly fallen to diabesity like never before? Darwin would have looked at the overnight doubling of rates of obesity and exclaimed, Cant be genetics! This is not to say that there is no genetic component to either condition, not to say that genetic research, along with the Genome Project, will not eventually enable physicians to better identify those at risk for these conditions. However, when you hear lecture after lecture, read article after article describing the suspense, the adventure of this manhunt for the answer to these problems, to be found in double-helix form, or within a cute little capsule, the disconnect becomes apparent: We are trying to solve a problem that is obviously behavior/lifestyle induced by other means (i.e. genetics, pharmaceuticals), willing to ignore the causal factors as unchangeable variables. Medicine, based on its focus, acts as if it is a congenital ...

We refine the OrbNet model to accurately predict energy, forces, and other response properties for molecules using a graph neural-network architecture based on features from low-cost approximated quantum operators in the symmetry-adapted atomic orbital basis. The model is end-to-end differentiable due to the derivation of analytic gradients for all electronic structure terms, and is shown to be transferable across chemical space due to the use of domain-specific features. The learning efficiency is improved by incorporating physically motivated constraints on the electronic structure through multi-task learning. The model outperforms existing methods on energy prediction tasks for the QM9 dataset and for molecular geometry optimizations on conformer datasets, at a computational cost that is thousand-fold or more reduced compared to conventional quantum-chemistry calculations (such as density functional theory) that offer similar accuracy. ...
