Carrió, MM and Villaverde, A (2005) Localization of chaperones DnaK and GroEL in bacterial inclusion bodies. J. Bacteriol. 187:3599-601

Abstract

By immunostaining and transmission electron microscopy, chaperones DnaK and GroEL have been identified at the solvent-exposed surface of bacterial inclusion bodies and entrapped within these aggregates, respectively. Functional implications of this distinct localization are discussed in the context of Escherichia coli protein quality control.
