Study of the arginine repressor in different organisms
... The arginine repressor (ArgR) regulates transcription of the arginine biosynthetic genes in bacteria. ArgR proteins play a multifunctional role in the bacterial cell. They inhibit biosynthetic promoters and are involved in activation of several catabolic pathways. The arginine repressor of Streptomy ...
