Polyphosphate accumulation and oxidative DNA damage in superoxide dismutase-deficient Escherichia coli.

Free radical biology & medicine - 1 Dec 2001

Al-Maghrebi M A, Benov L T

Abstract excerpt

Inorganic polyphosphate is a ubiquitous, linear polymer of phosphate residues linked by high-energy phosphoanhydride bonds. In response to starvation, polyP levels are increased up to 100-fold. It has been proposed that chelation of transition metals by polyP might reduce their toxicity, and that polyP accumulation is vital for survival in stationary phase. SOD-deficient E. coli is unable to survive in stationary...
