Localization of chaperones DnaK and GroEL in bacterial inclusion bodies

Localization of chaperones DnaK and GroEL in bacterial inclusion bodies

M Mar Carrió et al. J Bacteriol. 2005 May.

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.

FIG. 1.
In situ immunodetection of DnaK (A, B, C), GroEL (D, E, F), and β-galactosidase (J, K) in E. coli cells producing the inclusion body-forming protein VP1LAC. Double-detection images of DnaK (15-nm gold particles) and GroEL (10-nm gold particles) on VP1LAC-producing cells (G, H) and those expressing the parental, soluble beta-galactosidase (I) are also shown. Cells incubated only with the secondary anti-rabbit antibody (BBInternational EMGAR-10) are also shown as a control of the procedure (L). Horizontal bars depicted in the panels represent 200 nm.
