ArgP DNA-binding transcriptional dual regulator

Synonyms: ArgP, ArgP-arginine, ArgP-lysine
ArgP, for "arginine protein," controls the transcription of genes involved in the arginine transport system and genes involved in DNA replication. DNA replication is also regulated directly by ArgP when the protein binds to three 13-mers located in the origin of replication (OriC), which blocks the DNA opening by DnaA and inhibits this cellular process [3, 15, 16] DNA binding by ArgP is prevented when the serine protease Do (DegP) hydrolyzes this transcriptional regulator [17]. ArgP was first identified as an inhibitor of oriC-initiated DNA replication in vitro. It has also subsequently been described as a nucleoid-associated protein that shows apparently sequence-nonspecific DNA-binding activity [18] ArgP is a noncanonical regulator, as it binds to a number of additional sites in the genome without an apparent direct regulatory effect, exhibiting low-affinity binding to these additional sites [5, 13, 16] To activate transcription, ArgP recognizes AT-rich DNA-binding sites, but no consensus sequence has been identified.
