Cold-Shock Response in Escherichia coli 193 Cold Shock Response in Escherichia coli
Sensing a sudden change of the growth temperature, all living organisms produce heat shock proteins or cold shock proteins to adapt to a given temperature. In a heat shock response, the heat shock sigma factor plays a major role in the induction of heat shock proteins including molecular chaperones and proteases, which are well-conserved from bacteria to human. In contrast, no such a sigma fact...
متن کاملMajor cold shock protein of Escherichia coli.
When exponentially growing Escherichia coli cell cultures were transferred from 37 degrees C to 10 degrees C or 15 degrees C, the production of a 7.4-kDa cytoplasmic protein (CS7.4) was prominently induced. The rate of CS7.4 production reached 13% of total protein synthesis within 1-1.5 hr after a shift to 10 degrees C and subsequently dropped to a lower basal level. Regulation of CS7.4 express...
متن کاملRole of the ribosome-associated protein PY in the cold-shock response of Escherichia coli
Protein Y (PY) is an Escherichia coli cold-shock protein which has been proposed to be responsible for the repression of bulk protein synthesis during cold adaptation. Here, we present in vivo and in vitro data which clarify the role of PY and its mechanism of action. Deletion of yfiA, the gene encoding protein PY, demonstrates that this protein is dispensable for cold adaptation and is not res...

متن کاملCold-shock Protein Expression System Facilitates the Solubility of Human ST6Gal I in Escherichia Coli
The protein structures of most mammalian sialyltransferases have yet to be elucidated. Practical and convenient protein expression systems for soluble and active sialyltransferases will facilitate elucidation of the protein structures and catalytic mechanisms of these enzymes. The present study was performed to establish an efficient expression system for human ST6Gal I (hST6Gal I). cDNA encodi...
