Description
Summary:Made available in DSpace on 2015-04-14T14:49:54Z (GMT). No. of bitstreams: 1 443882.pdf: 1538805 bytes, checksum: 0ca0fe774889aa54673d3442302094d2 (MD5) Previous issue date: 2010-08-31 === PEDS can be used in research activities and in the teaching of molecular modeling, being enough flexible to be integrated to other software of molecular docking. The preparation and Execution of Docking Simulation (PEDS), is auxiliary tool in preparation of a set of molecules obtained from the ZINC database, automatically positioning the ligand candidate in a region determined by the specialist using the residues of the ligand candidate to calculate the coordinates to move it to. Based on this information, PEDS can prepare scripts e execute the molecular docking to run with AutoDock 3.0.5. PEDS was validated using InhA as receptor in two conformations, (1ENY e 1BVR), always with same structure as reference and two ligands, TCL and ETH. It was possible to verify that molecular docking moved the ligand near to active site of receptor, using the position calculated by PEDS. PEDS can be enhanced to use another input and output file formats, having its code available for free distribution. === O PEDS pode ser utilizado nas atividades de pesquisa bem como no ensino de modelagem molecular sendo suficientemente flex?vel para ser integrado a outros programas de docagem molecular.

O PEDS foi validado utilizando-se o receptor InhA em duas conforma??es (1ENY e 1BVR), sempre com uma estrutura de refer?ncia e dois ligantes, o TCL e a ETH. Foi poss?vel verificar que a docagem molecular colocou o ligante pr?ximo ao s?tio ativo, partindo da posi??o calculada pelo PEDS. O PEDS pode ser aprimorado para utiliza??o de outros formatos de arquivos de entrada e sa?da, sendo seu c?digo fonte dispon?vel para distribui??o.
