Tertiary Structure
This page has been created to search the peptides using structure input. The page can accept the input in major file formats (PDB, Smiles). User can also draw their stucture using Marvin applet. The page will further process the input file with the user-selected options using JCsearch program at the backend and the results will be provided in an attractive passion. The PDB input option is set to default.

Frequently Asked Questions (FAQs)


Q1. What is SATPdb?
Ans . SATPdb is a database of structurally annotated peptides.

Q2. Why SATPdb?
Ans. It comprising peptide entries from most of the peptide databases currently available to the scientific community. It will give all the information about a peptide. A person may be intrested to see whether an antimicrobial peptide also have other properties like cell penentarting, hemolytik, anti cancerous. This database will helpfull to relate all the peptide characterstic with each other.

Q3. How to search into SATPdb?
Ans. A user can perform sequence or secondary structure-based searching to identify identical/similar entries present in all the peptide databases integrated in SATPdb.
