Protein

Nitrogen regulation protein NR(I)

Gene

glnG

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Member of the two-component regulatory system NtrB/NtrC involved in the activation of nitrogen assimilatory genes such as GlnA. NtrC is phosphorylated by NtrB and interacts with sigma-54.
