Identification , characterization , and DNA sequence of a functional " double " groES-like chaperonin from chloroplasts of higher plants ( molecular chaperones / stres proteins / groEL / protein import / pro folding )

  • PAUL V. VIITANENt

Abstract

Chloroplasts of higher plants contain a nuclear-encoded protein that is a functional homolog of the Escherichia coli chaperonin 10 (cpnlO; also known as groES). In pea (Pisum satvum), chloroplast cpnlO was identified by its ability to (i) assist bacterial chaperonin 60 (cpn60; also known as groEL) in the ATP-dependent refolding of chemically denatured… (More)
