Impaired oxidative stress resistance of Bacillus subtilis sigB mutants and the role of katA and katE.

FEMS microbiology letters - 15 Nov 1996

Engelmann S, Hecker M

Abstract excerpt

Two catalases of B. subtilis have been studied which are subject to two different regulatory mechanisms. Whereas KatA belongs to the group of proteins specifically induced by oxidative stress, KatE is a general delta B-dependent stress protein, not induced by oxidative stress. There are two mechanisms of oxidative stress resistance, the adaptive resistance induced by low H2O2 concentrations and an unspecific...
