Alanine-scanning mutagenesis library of MreB reveals distinct roles for regulating cell shape and viability.

Abstract excerpt

The bacterial actin-homolog MreB is a crucial component of the Rod-system (elongasome) that maintains rod shape in many bacteria. It is localized beneath the cytoplasmic membrane, where it organizes the elongasome complex. Depletion or deletion of mreB results in loss of rod shape and cell death; however, the mechanism of how MreB operates is not known. Past studies have reported that mutations in mreB cause...
