Abstract excerpt
In eubacteria and mitochondria, Hsp70 chaperone activity is controlled by the nucleotide exchange factor GrpE. We have identified the chloroplastic GrpE homolog of Chlamydomonas, CGE1, as an approximately 26-kD protein coimmunoprecipitating with the stromal HSP70B protein. When expressed in Escherichia coli, CGE1 can functionally replace GrpE and interacts physically with DnaK. CGE1 is encoded by a single-copy...
