Abstract
A hisG gene, encoding ATP phosphoribosyl phosphothansferase, insertion mutation was found to effected the production of four different proteins in Salmonella Typhimurium LT2 as a results of comparative analysis of two-dimensional analysis of hisG mutant (Δhis87) and the conrol strain (LT2). MALDI-TOF analysis of these protein spots which were expresed in S. Typhimurium LT2 but not its mutant Δhis87, showed that these proteins were; GMP synthase, arginine-tRNA ligase (Arginyl-tRNA synthetase), SopE and SifA. All of these proteins are virulence-associated proteins in Salmonella. Thus we have concluded that the proper function of histidine operon is very crucial for virulence of S. Typhimurium.
