Cold-shock response and adaptation.
The most common stress that living organisms constantly confront in nature is likely to result from temperature changes. Figure 1 shows the temperature changes in Newark, New Jersey during a one year period. The graph shows both average highest and lowest temperatures of each month as indicated by open and solid circles, respectively. One can see that per month there is a difference of approxim...
متن کاملCold-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 کاملIdentification and transcriptional control of Caulobacter crescentus genes encoding proteins containing a cold shock domain.
The cold shock proteins are small peptides that share a conserved domain, called the cold shock domain (CSD), that is important for nucleic acid binding. The Caulobacter crescentus genome has four csp genes that encode proteins containing CSDs. Three of these (cspA, cspB, and cspC) encode peptides of about 7 kDa and are very similar to the cold shock proteins of other bacteria. Analysis by reve...
متن کاملProtein oxidation in response to increased transcriptional or translational errors.
In this study, we show a correlation between synthesis of aberrant proteins and their oxidative modification. The level of aberrant proteins was elevated in Escherichia coli cultures by decreasing transcriptional or translational fidelity using specific mutations or drugs. Protein carbonylation, an oxidative modification, increased in parallel to the induction of the heat shock chaperone GroEL....
متن کاملCSDBase: an interactive database for cold shock domain-containing proteins and the bacterial cold shock response
CSDBase (http://www.chemie.uni-marburg.de/~csdbase/) is an interactive Internet-embedded research platform providing detailed information on proteins containing the cold shock domain (CSD). It consists of two separated database cores, one dedicated to CSD protein information, and one to provide a powerful resource to relevant literature with emphasis on the bacterial cold shock response. In add...
