In silico Analysis of Structure and Function of Hypothetical Proteins in Salmonella typhimurium (SL1344)

Abstract

Salmonella typhimurium strain SL1344(S.typhi) is a non typhoidal bacteria which may cause infection in human gastrointestinal tract, may cause abdominal pain, fever, diarrhea, and inflammation some times which may lead to the human death. A comparative study of hypothetical outer membrane proteins of Salmonella typhimurium strain SL1344 (S.typhi) was performed using bioinformatic tools. Bioinformatics is a source to analyse whole genomic sequence of a vast number of uncharacterized genes. Online databases like UniProt, String, Pfam and other tools were used. Thirteen uncharacterized and hypothetical protein present in outer membrane of the bacteria S.typhi were retrieved from UniProt and its structure and function were studied. In this study the cellular function, pathway of enzyme interaction, antibiotic resistance were analyzed. The structure of the protein as well the function of these proteins provides better understanding to perform molecular docking and identification of small molecule inhibitors.
