Influence of Escherichia coli DnaK and DnaJ molecular chaperones on tryptophanase (TnaA) amount and GreA, GreB stability.

Abstract excerpt

The amount of tryptophanase was estimated in Escherichia coli deltadnaJ and deltadnaKdnaJ mutants. Densitometric analysis of polyacrylamide gels demonstrated that the amount of tryptophanase was diminished in both mutants. DnaK and DnaJ molecular chaperones apparently influence the amount of tryptophanase, the expression of which is regulated at all transcription steps, including transcription elongation. The...
