Heme A synthase enzyme functions dissected by mutagenesis of Bacillus subtilis CtaA.
Heme A, as a prosthetic group, is found exclusively in respiratory oxidases of mitochondria and aerobic bacteria. Bacillus subtilis CtaA and other heme A synthases catalyze the conversion of a methyl side group on heme O into a formyl group. The catalytic mechanism of heme A synthase is not understood, and little is known about the composition and structure of the enzyme. In this work, we have:...
متن کاملTwo ResD-controlled promoters regulate ctaA expression in Bacillus subtilis.
The Bacillus subtilis ResDE two-component system plays a positive role in global regulation of genes involved in aerobic and anaerobic respiration. ctaA is one of the several genes involved in aerobic respiration that requires ResD for in vivo expression. The ctaAB-divergent promoter regulatory region has three ResD binding sites; A1, A2, and A3. The A2 site is essential for in vivo promoter ac...
متن کاملChloramine mutagenesis in Bacillus subtilis.
Chloramine (which occurs widely as a by-product of sanitary chlorination of water supplies) is shown to be a weak mutagen, when reversion of trpC to trpC in Bacillus subtilis is used as an assay. Some DNA-repair mutants appear to be more sensitive to chloramine, suggesting the involvement of DNA targets in bactericide. The influence of plating media on survival of cells treated with chloramine ...
متن کاملIn vitro elaboration Mutagenesis and cloning of the PA gene in Bacillus subtilis
Background: The immune antigen of Bacillus anthracis is a protein that can attach to the surface receptor of all human cells. At the surface of cancer cells, there is a receptor that activates the uPA (Urokinase plasminogen) that do not exist in normal human cells. Objectives: The aim of this study was changing the location of the attachment of the PA gene by a dir...
