Protein Modelling

CPSSD: (Compact Protein secondary structure Database): allows one to extract protein secondary structure information from DSSP files to create protein secondary structure database in compact and user friendly format.

ASSP: (Assessment of secondary structure prediction): has been developed for evaluating the quality of protein secondary structure prediction and for appraising the secondary structure prediction methods.

ONNM: (Optimized Nearest Neighbour Method): was developed to predict the protein secondary structure from their amino acid sequence. It first predicts the secondary structure by combining netural network and nearest neghbour approach.

PSSPR: (Prediction of Protein Conformational States): A 64 conformational states prediction method has been developed to predict the dihedral angle of protein backbone.

CATSP: (Computer Aided Tertiary Structure Prediction): This program used the dihedral angles of protein backbone and secondary structure information and generate the Cartesian coordinate of tertiary structure of protein. This program also allow to use the rotamer library (Dunbark and Karplus) to compute the sidechain angles.

Molecular Biology

DNASIZE: This computer program has been developed for computing the size of DNA fragments from their electrophoretic mobilities using a graphical method. This program can also be used to compute the size of proteins or polypeptides from SDS-PAGE. In addition to computing the size of DNA fragments and protein size the program also allows one to present the comparison of standard curves obtained from gel electrophoresis (or SDS-PAGE). The program is written in C and can be run on IBM PC or a compatible computer under MS-DOS version 2.0 or higher, and requires a CGA, EGA or VGA card. Click to down load t his program.

GMAP: A comprehensive computer program GMAP, has been developed for mapping the potential restriction endonuclease (R. E.) sites in non-ambiguous DNA sequence, predicting the number and type of mutations required to introduce unique R.E. sites in the non-ambiguous, searching all R.E. sites in ambiguous DNA sequence obtained by reverse translation of a given amino acid sequence; iv) searching R.E. sites in DNA sequence obtained from reverse translation of amino acid sequence employing user-defined codon usage. These facilities allow the program to be employed for the design of synthetic genes as well as the modular redesign of gene.Click to down load this program.
