Peptide-assisted degradation of the Salmonella MgtC virulence factor.
MgtC is a virulence factor common to several intracellular pathogens that is required for intramacrophage survival and growth in magnesium-depleted medium. In Salmonella enterica, MgtC is coexpressed with the MgtB magnesium transporter and transcription of the mgtCB operon is induced by magnesium deprivation. Despite the high level of mgtCB transcriptional induction in magnesium-depleted medium...
متن کاملThe MgtC virulence factor of Salmonella enterica serovar Typhimurium activates Na(+),K(+)-ATPase.
The mgtC gene of Salmonella enterica serovar Typhimurium encodes a membrane protein of unknown function that is important for full virulence in the mouse. Since mgtC is part of an operon with mgtB which encodes a Mg(2+)-transporting P-type ATPase, MgtC was hypothesized to function in ion transport, possibly in Mg(2+) transport. Consequently, MgtC was expressed in Xenopus laevis oocytes, and its...
متن کاملCharacterization of MgtC, a Virulence Factor of Salmonella enterica Serovar Typhi
The MgtC is a virulence factor in Salmonella Typhimurium that is required for growth at low-Mg2+ concentrations and intramacrophage survival. This gene is codified in a conserved region of the Salmonella pathogenicity island 3 (SPI-3), and is also present in the chromosome of other Salmonella serovars. In this study we characterized the MgtC factor in S. Typhi, a human specific pathogen, by usi...

15 صفحه اولThe C-terminal domain of the virulence factor MgtC is a divergent ACT domain.
MgtC is a virulence factor of unknown function important for survival inside macrophages in several intracellular bacterial pathogens, including Mycobacterium tuberculosis. It is also involved in adaptation to Mg(2+) deprivation, but previous work suggested that MgtC is not a Mg(2+) transporter. In this study, we demonstrated that the amount of the M. tuberculosis MgtC protein is not significan...
