Abstract excerpt
Nitrogen regulator I (NRI [or NtrC])-phosphate stimulates transcription from the glnAp2 promoter of the glnALG operon in enteric bacteria. Unlike most activators, NRI-phosphate can stimulate transcription without apparent activator binding sites. We observed that when lacZ was controlled by a minimal glnAp2 promoter (without NRI binding sites) in Escherichia coli, lacZ expression was regulated by two different...
