Abstract:
Frequency distributions of protein backbone dihedral angles φ and ψ have been analyzed systematically for their apparent correlation with various crystallographic parameters, including the resolution at which the protein structures had been determined, the R factor and the free R factor, and the results have been displayed in novel differential Ramachandran maps. With improved sensitivity compared with conventionally derived heuristic Ramachandran maps, such differential maps automatically reveal conformational `attractors' to which φ/ψ distributions converge as the crystallographic resolution

Abstract:
The Protein Data Bank (PDB) is the most important depository of protein structural information, containing more than 45,000 deposited entries today. Because of its inhomogeneous structure, its fully automated processing is almost impossible. In a previous work, we cleaned and re-structured the entries in the Protein Data Bank, and from the result we have built the RS-PDB database. Using the RS-PDB database, we draw a Ramachandran-plot from 6,593 "perfect" polypeptide chains found in the PDB, containing 1,192,689 residues. This is a more than tenfold increase in the size of data analyzed before

Abstract:
The full conformational space of N-formyl-L-alanine-amide was explored by the semi-empirical method AM1 coupled to the Multi Niche Crowding (MNC) genetic algorithm implemented in a package of programs developed in our laboratory. The structural and energy analysis of the resulting conformational space E(,ψ) exhibits 5 regions or minima ɣL, ɣD, ɛL, D and αD. The technique provides better detection of local and global minima within a reasonable time.

Abstract:
Conformational preferences of Ac-deltaAla-NMe2 and Ac-(Z)-deltaPhe-NMe2 were studied and compared with those of their monomethyl counterparts as well as with those of their saturated analogues. X-Ray data and energy calculations revealed a highly conservative conformation of the dehydro dimethylamides, which is located in a high-energy region of the Ramachandran map.

Abstract:
Three investigators, with varying levels of experience, independently built and refined the structure of Escherichia coli ribokinase at 2.6 Å resolution. At the end of the refinement/rebuilding processes the models had essentially converged, although each had its own particular pattern of remaining errors. The subsequent refinement of the same structure at 1.8 Å resolution allowed an overall quality check of each of the lower resolution models, and an analysis of which graphics-based tools were generally most efficient in locating these errors.

Abstract:
The Ramachandran steric map of torsion angles (φ, ψ) introduced in 1963 has been widely used for protein structure validation and model building. Many developments in the field have made it essential to develop a utility to plot assorted types of maps for the following specific reasons: (i) to investigate different types (Gly, Val/Ile, pre/trans/cis-Pro and general) of 2D and 3D maps, addressing the diverse steric environments and frequency distribution of conformations, (ii) to examine polypeptides containing non-standard residues, (iii) for better visualization and analysis of conformational

Abstract:
Synthetic construction of protein molecules has been widely pursued over the last two decades. A primary goal behind de novo protein design has been to build minimal systems by capturing the essential features of protein structures. Such minimal models can be used to understand underlying principles governing folding, structure, and function of proteins molecules. Several approaches envisioning successful construction of synthetic proteins have been described over the years, some of them being admirably successful (DeGrado et al, 1999; Richardson et al> 1992; Baltzer, 1998).

Faptul ca am ales sa scriu despre minciuna nu este aleator. Scriu despre minciuna pentru ca vreau sa contribui la o viata mai buna pentru semenii mei. Stiu ca daca nu reusesti sa o identifici, iti va fi dificil sa o probezi. Este important sa traiesti cat mai curat, dar si sa fi trecut prin perioade in care ai mintit. Minciuna nu poate fi inteleasa de la un amfiteatru virtual de unde se dau lectii de morala si etica.

Abstract:
A trio of themes recur across prominent Western theories of laughter: violence, the human/nonhuman, and error. The paper traces this trio through a series of frequently cited paradigms for understanding laughter, including superiority, incongruity and relief theories, Henri Bergson’s theory of laughter and V. S. Ramachandran’s false alarm theory; and argues that it reflects a shared, if partially submerged concern with the instability and demise of a particular figure of the human, one that is circumscribed by the culturally specific (if globally influential) values of Eurocentric/Western thou
