Characterization of OxyR as a negative transcriptional regulator that represses catalase production in Corynebacterium diphtheriae.

PloS one - 1 Jan 2012

Kim Ju-Sim, Holmes Randall K

Abstract excerpt

Corynebacterium diphtheriae and Corynebacterium glutamicum each have one gene (cat) encoding catalase. In-frame Δcat mutants of C. diphtheriae and C. glutamicum were hyper-sensitive to growth inhibition and killing by H(2)O(2). In C. diphtheriae C7(β), both catalase activity and cat transcription decreased ~2-fold during transition from exponential growth to early stationary phase. Prototypic OxyR in Escherichia...
