Catalase HPI influences membrane permeability in Escherichia coli following near-UV stress.

Biochemical and biophysical research communications - 28 Sept 1990

Levén S, Heimberger A, Eisenstark A

Abstract excerpt

The katG gene in Escherichia coli encodes catalase HPI, which is involved in membrane transport and protects the cell during oxidative stress. Hydrogen peroxide (H2O2) induces synthesis of HPI. We examined the role of HPI in membrane permeability (proline uptake) following exposure to near-ultraviolet radiation (NUV). We found that NUV resulted in the same type of induction as H2O2. KatG::Tn10 cells experienced a...
