Abstract

The expression of a vegetative catalase gene, katA (formerly the kat-19 gene), is necessary to protect Bacillus subtilis from H2O2, presumably by removing the oxidant from the environment. Genetic analysis of katA revealed that this gene is under two distinct forms of regulation, temporal and H2O2 inducible. The results reported here demonstrate that (i) the H2O2-inducible regulation of katA gene is not a component of the SOS regulon, (ii) the regulatory genes spo0A and abrB are involved in the temporal regulation but not the H2O2-specific induction of katA gene expression, and (iii) transcription initiation for the katA gene occurs at the same site under both forms of regulation.

摘要

一种营养型过氧化氢酶基因katA(以前称为kat - 19基因)的表达对于保护枯草芽孢杆菌免受H2O2的侵害是必需的,大概是通过从环境中去除氧化剂来实现。katA的遗传分析表明,该基因受两种不同形式的调控,即时间调控和H2O2诱导调控。此处报道的结果表明:(i)katA基因的H2O2诱导调控不是SOS调控子的组成部分;(ii)调控基因spo0A和abrB参与时间调控,但不参与katA基因表达的H2O2特异性诱导;(iii)katA基因的转录起始在两种调控形式下都发生在同一位置。
