Expression and role of the universal stress protein, UspA, of Escherichia coli during growth arrest.

Abstract excerpt

The synthesis of the small, cytoplasmic protein UspA universal stress protein A) of Escherichia coli is induced as soon as the cell growth rate falls below the maximal growth rate supported by the medium, regardless of the condition inhibiting growth. The increase in UspA synthesis appears to be the result of induction of the monocistronic uspA gene. Induction of this gene during a heat-shock treatment is...
