[The role of antioxidant systems in response of bacteria Escherichia coli to heat shock].

Mikrobiologiia - 1 Jan 2000

Smirnova G V, Zakirova O N, Oktiabr'skiĭ O N

Abstract excerpt

Shifting the temperature from 30 to 45 degrees C in an aerobic Escherichia coli culture inhibited the expression of the antioxidant genes katG, katE, sodA, and gor. The expression was evaluated by measuring beta-galactosidase activity in E. coli strains that contained fusions of the antioxidant gene promoters with the lacZ operon. Heat shock inhibited catalase and glutathione reductase, lowered the intracellular...
