Chaperone DnaJ Influences the Formation of Biofilm by Escherichia coli.

DnaJ chaperone, a member of the so called DnaK-DnaJ-GrpE chaperone machine plays an important role in cell physiology. The ability of Escherichia coli ΔdnaJ mutant to form biofilm was studied. It was shown that this mutant is impaired in biofilm development when exposed to 42 degrees C for 2 h.
