Conformational changes in bacterial polysomes induced by amino acid starvation

E Andrieux et al. Int J Biochem. 1984.

Abstract

The effects of amino acid starvation on polysome conformation were analyzed comparatively in stringent (relA+) and relaxed (relA) bacteria by measuring the accessibility in vitro of ribosomal proteins to reductive methylation. In polysomes of stringent cells, the conformational state of two proteins (L13 and L29) appeared significantly changed by starvation. In polysomes isolated from relaxed mutants, the accessibility of five proteins (L5, L13, L29, L31 and L32) was found modified.
