| Description | Purity ≥ 90% as determined by SDS-PAGE analysis. Purified from an E. coli strain over-expressing GrpE. GrpE is an acidic 24kD protein which is encoded by a monocistronic Escherichia coli gene (located at 56 min.) which is under the control of both s32 and s70 transcription factors (1). The GrpE protein is a so-called co-chaperone because it is known to assist the DnaK (Hsp70) protein to effectively carry out DnaK-dependent chaperone activity (i.e. protein folding, protein transport, disaggregation of heat inactivated proteins, activation of mutant protein). This auxiliary role is critical to DnaK's chaperone biology since the grpE gene could not be deleted in a wild type background unless the host E. coli were previously adapted for deletions of the DnaK gene through the accumulation of extragenic suppressers. Also, in vitro these two proteins functionally interact; GrpE protein forms a salt resistant complex with DnaK protein, which is disrupted by ATP (1). It is suggested that DnaK |
