چکیده
The gene encoding nucleosidediphosphate kinase (ndk) was located at 55 units on the Salmonella typhimurium chromosome. The ndk locus was 83% cotransducible with hisS and 2% cotransducible with glyA in phage P22-mediated crosses. A nucleosidediphosphate kinase mutant that produced only 10% of the wild-type enzyme activity (ndk-1) grew normally and produced a heat-labile enzyme.

Location of the gene (ndk) for nucleoside diphosphate kinase on the physical map of the Escherichia coli chromosome.
Nucleoside diphosphate kinase is essential to maintain the cellular concentrations of all nucleoside triphosphates and deoxynucleoside triphosphates at functional levels (3). The gene (ndk) for this enzyme from Myxococcus xanthus has been cloned, and its DNA sequence has been determined (8, 9). A genetic experiment indicated that the ndk gene is essential for cell growth of M. xanthus (8, 9). R...
متن کاملNucleoside diphosphokinase of Salmonella typhimurium.
Nucleoside diphosphokinase from Salmonella typhimurium has been purified and characterized. In many respects, the enzyme is similar to those from higher organisms in that it has a broad speciCcity for both phosphate donor and recipient and that it functions via a ping-pong mechanism. The enzyme activity of cells is very high at all growth rates but decreases as growth rate increases. Evidence i...

Background: Salmonella belongs to the family of Enterobacteriaceae, an intestinal, gram negative, and anaerobic bacterium. Salmonella affects a wide range of vertebrates, mainly through direct and indirect contact with the infected source. Salmonellosis is a dangerous infectious disease and a common human-animal disease. The integron (int) gene is effective in drug resistance and bacterial prol...

Background & Aims: Salmonella Typhimurium is a negative-gram, non-spore, free capsule, moving bacteria with Trish Perry flagella. Salmonella is the most common cause of food poisoning. The ability to enter and survive in host cells is the condition for pathogenic Salmonella species. Proteins of invasive Salmonella are transferred to the host cells by bacteria. This study was performed for gener...
