Received 10 January 2005/ Accepted 31 January 2005

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.
