Polyamines reduce paraquat-induced soxS and its regulon expression in Escherichia coli.

Cell biology and toxicology - 1 Feb 2003

Jung I L, Kim I G

Abstract excerpt

Polyamines, ubiquitous polycationic compounds, are involved in many cellular responses and relieve paraquat-induced cytotoxicity in Escherichia coli. We constructed a new E. coli mutant strain, JIL528, which is deficient in the biosynthesis of both putrescine and spermidine, to examine the physiological role of polyamines under oxidative stress caused by paraquat. Putrescine and spermidine downregulate the...
