Essential role of flavohemoglobin in long-term anaerobic survival of Bacillus subtilis.
نویسنده
چکیده
A Bacillus subtilis culture incubated anaerobically in nitrate-containing medium lost viability during the first 3 days but recovered thereafter. A flavohemoglobin mutant showed very poor survival under these conditions unless the cells were prevented from carrying out nitrate respiration.

Oxygen-controlled regulation of the flavohemoglobin gene in Bacillus subtilis.
A gene, hmp, which encodes a ubiquitous protein homologous to hemoglobin was isolated among genes from Bacillus subtilis that are induced under anaerobic conditions. The hmp protein belongs to the family of two-domain flavohemoproteins, homologs of which have been isolated from various organisms such as Escherichia coli, Alcaligenes eutrophus, and Saccharomyces cerevisiae. These proteins consis...
متن کاملModulation of anaerobic energy metabolism of Bacillus subtilis by arfM (ywiD).
Bacillus subtilis grows under anaerobic conditions utilizing nitrate ammonification and various fermentative processes. The two-component regulatory system ResDE and the redox regulator Fnr are the currently known parts of the regulatory system for anaerobic adaptation. Mutation of the open reading frame ywiD located upstream of the respiratory nitrate reductase operon narGHJI resulted in elimi...
متن کاملMechanisms of adaptation to nitrosative stress in Bacillus subtilis.
Bacteria use a number of mechanisms for coping with the toxic effects exerted by nitric oxide (NO) and its derivatives. Here we show that the flavohemoglobin encoded by the hmp gene has a vital role in an adaptive response to protect the soil bacterium Bacillus subtilis from nitrosative stress. We further show that nitrosative stress induced by the nitrosonium cation donor sodium nitroprusside ...
متن کاملThe nitric oxide-responsive regulator NsrR controls ResDE-dependent gene expression.
The ResD-ResE signal transduction system is essential for aerobic and anaerobic respiration in Bacillus subtilis. ResDE-dependent gene expression is induced by oxygen limitation, but full induction under anaerobic conditions requires nitrite or nitric oxide (NO). Here we report that NsrR (formerly YhdE) is responsible for the NO-dependent up-regulation of the ResDE regulon. The null mutation of...
متن کاملThe Bacillus subtilis nrdEF genes, encoding a class Ib ribonucleotide reductase, are essential for aerobic and anaerobic growth.
Ribonucleotide reductases (RNRs) are essential for the biosynthesis of the deoxyribonucleoside triphosphates of DNA. Recently, it was proposed that externally supplied deoxyribonucleosides or DNA is required for the growth of Bacillus subtilis under strict anaerobic conditions (M. J. Folmsbee, M. J. McInerney, and D. P. Nagle, Appl. Environ. Microbiol. 70:5252-5257, 2004). Cultivation of B. sub...
