Protein Variants

Protein Variants Comment Organism
additional information genotyping of different strains from M and G populations, overview. The only mutated gene shared between the strains from populations M and G is bll4572, this gene encodes the Bll4572 protein and is mutated in all six strains. Regulation of nos and nap genes by the NasST system in the absence or presence of nitrate in mutant strains, overview. NasS and NasT form a stable complex that is sensitive to the presence of NO3-/NO2-. Binding of NO3-/NO2- by the sensor NasS triggers the release of NasT, which binds the leader sequence upstream of the nas operon, thereby preventing hairpin formation and allowing complete transcription of the nas operon Bradyrhizobium japonicum

Expression

Organism Comment Expression
Bradyrhizobium japonicum disruption of nasT leads to a marked decrease in nosZ and nap transcription in cells incubated in the presence of nitrate down
Bradyrhizobium japonicum in the absence of nitrate, mutated nasS, which encodes the nitrate (NO3-)-sensor of the two-component NasST regulatory system, induces expression of nosZ and periplasmic nitrate reductase nap via nasT. Nitrate addition dissociates the NasS-NasT complex in vitro, suggesting the release of the activator NasT up
