The gram-positive endospore-forming bacterium Bacillus subtilis has, under aerobic conditions, a branched respiratory system comprising one quinol oxidase branch and one cytochrome oxidase branch. The system terminates in one of four alternative terminal oxidases. Cytochrome caa(3) is a cytochrome c ...
Further, the lack of relationship between polyphenol oxidases and polyphenol content suggests that POs alone do not control the fate of these compounds along this thaw gradient. Given this and the positive relationship observed between polyphenol abundance and porewater CO2 concentrations, our data ...
subtilis chromosome. >90% of the erythromycin-resistant transformants obtained when strain 1A1C was transformed with limiting amounts of LUL9 chromosomal DNA were found to be chloramphenicol-sensitive. Cytochrome c Oxidase Activity Assay Isolated membranes fromB. subtilis strains were added at a final...
A patient, suspected to have bacterial endocarditis, had two sets of blood cultures drawn. All four bottles are positive with gram-positive cocci in pairs and chains. On sheep blood agar, the gray, transparent, alpha-hemolytic colonies are catalase negati This bioche...
24The PG peptide stem often contains D-Ala residues at the fourth and fifth positions.25The disruption of the synthesis of these two residues could lead to the cell death of Gram-positiveBacillusandLactobacillus.6,26In Gram-positive bacteria, such asBacillus subtilisandStaphylococcusaureus, the ...
Plants utilize the D-mannose/L-galactose pathway to synthesize ascorbate (ASC), while animals produce both ascorbate (ASC) and hydrogen peroxide (H2O2) via the UDP-glucose pathway, with the final step catalyzed by Gulono-14-lactone oxidases (GULLO). Posted in Uncategorized | Leave a reply ...
Furthermore, this domain is also found in subunits of enzymes, such as succinate:quinone oxidoreductase, glycolate oxidase and anaerobic glycerol-3-phosphate dehydrogenase, that are widespread in many organisms not related to sulfur metabolism [6], [7]. Many of these proteins are membrane-...
We have found that two DNA repair/recombination proteins localize differentially to the cell poles in competent Bacillus subtilis cells. RecA protein colocalized with competence protein ComGA, and its polar localization largely depended on ComGA and ComK activity, while RecN oscillated between the pol...
Since deacetylation of GlcNAc residues increases the cell wall net positive charge, it might lead to neutralization of negative charges conferred by GroP moieties and as a result, affect the translocation of cationic AMPs across the cell wall. To understand how modulation of the cell wall net ...
The expression of a vegetative catalase gene, katA (formerly the kat-19 gene), is necessary to protect Bacillus subtilis from H2O2, presumably by removing ... DK Bol,RE Yasbin - 《Journal of Bacteriology》 被引量: 97发表: 1994年 Defects in a quinol oxidase lead to loss of KatC catalase...
