چکیده

The Secondary Structural Elements of Proteins (SSEP) database is an integrated and comprehensive knowledge base for accessing information related to all the secondary-structural elements present in non-redundant (25 and 90%) protein chains. The new version 2.0 of the database contains 2485 and 8595 protein chains from the 25 and 90% non-redundant data sets, respectively. The necessary web interfaces have been developed that enable users to visualize the three-dimensional structure of the secondary-structural element in the client machine using the free molecular-visualization program RASMOL. This source is updated at regular intervals and can be accessed through the bioinformatics web server at the URL http://cluster.physics.iisc.ernet.in/ssep or http://144.16.71.148/ssep/.

SSEP-Domain: protein domain prediction by alignment of secondary structure elements and profiles

MOTIVATION The prediction of protein domains is a crucial task for functional classification, homology-based structure prediction and structural genomics. In this paper, we present the SSEP-Domain protein domain prediction approach, which is based on the application of secondary structure element alignment (SSEA) and profile-profile alignment (PPA) in combination with InterPro pattern searches....

Seismic Response of Building Structures with Sliding Non-structural Elements

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...

Thermodynamic-Biochemical Study of Complexes of Intermediate Elements with α-Amino Acids in Some Proteins with Active Site

In this paper, the quantum chemistry calculations related to the structural parameter of the chromite and molybdate anions and the complexes obtained from them with the glycine and alanine amino acids were performed. The calculations were carried out using HF and DFT methods and in the base series 6-31G *. Thermodynamic studies related to the formation of complexes have been considered and thei...

Improved method for prediction of protein backbone U-turn positions and major secondary structural elements between U-turns.

A new and more accurate method has been developed for predicting the backbone U-turn positions (where the chain reverses global direction) and the dominant secondary structure elements between U-turns in globular proteins. The current approach uses sequence-specific secondary structure propensities and multiple sequence information. The latter plays an important role in the enhanced success of ...
