DNA binding of Escherichia coli arginine repressor mutants altered in oligomeric state.

Molecular microbiology - 1 Jun 1997

Chen S H, Merican A F, Sherratt D J

Abstract excerpt

The Escherichia coli arginine repressor (ArgR) controls expression of the arginine biosynthetic genes and acts as an accessory protein in Xer site-specific recombination at cer and related plasmid recombination sites. The hexameric wild-type protein shows L-arginine-dependent DNA binding. In this work, ArgR mutants that are defective in trimer-trimer interactions and bind DNA as trimers in an...
