Cooperative MetR binding in the Escherichia coli glyA control region. 1996

Department of Microbiology, University of Iowa, Iowa City 52242, USA.

We determined the relative binding affinity of the MetR protein for wild-type and mutant MetR binding sites 1 and 2 in the Escherichia coli glyA control region. The results show that MetR binding site 1 has a higher affinity for the MetR protein than binding site 2. In addition, the results suggest that binding of MetR to the glyA promoter is cooperative. Mutations that decrease the ability of MetR to bind to either site 1 or site 2 have no significant effect on MetR's ability to bend DNA.

D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
D004269	DNA, Bacterial	Deoxyribonucleic acid that makes up the genetic material of bacteria.	Bacterial DNA
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
