ABSTRACT
UNLABELLED: Detailed structural analysis of protein necessitates investigation at primary, secondary and tertiary levels, respectively. Insight into protein secondary structures pave way for understanding the type of secondary structural elements involved (α-helices, ß-strands etc.), the amino acid sequence that encode the secondary structural elements, number of residues, length and, percentage composition of the respective elements in the protein. Here we present a standalone tool entitled "ExSer" which facilitate an automated extraction of the amino acid sequence that encode for the secondary structural regions of a protein from the protein data bank (PDB) file. AVAILABILITY: ExSer is freely downloadable from http://code.google.com/p/tool-exser/
ABSTRACT
UNLABELLED: Rapid genome sequencing enriched biological databases with enormous sequence data. Yet it remains a daunting task to unravel this information. However experimental and computational researchers lead their own way in analyzing sequence information. Here we introduce a standalone portable tool named "SeqCalc" that would assist the research personnel in computational sequence analysis and automated experimental calculations. Although several tools are available online for sequence analysis they serve only for one or two purposes. SeqCalc is a package of offline program, developed using Perl and TCL/Tk scripts that serve ten different applications. This tool would be an initiative to both experimental and computational researchers in their routine research. SeqCalc is executable in all windows operating systems. AVAILABILITY: SeqCalc can be freely downloaded at http://code.google.com/p/seqcalc.
ABSTRACT
WE DEVELOPED, TNAURICE: a database comprising of the rice varieties released from a public institution, Tamil Nadu Agricultural University (TNAU), Coimbatore, India. Backed by MS-SQL, and ASP-Net at the front end, this database provide information on both quantitative and qualitative descriptors of the rice varities inclusive of their parental details. Enabled by an user friendly search utility, the database can be effectively searched by the varietal descriptors, and the entire contents are navigable as well. The database comes handy to the plant breeders involved in the varietal improvement programs to decide on the choice of parental lines. TNAURice is available for public access at http://www.btistnau.org/germdefault.aspx.
