All oxidase-negative bacteria fell into groups III and IV. Bacteria in group III had low but still measurable TMPD oxidase rates, the Qo2 values ranging from 3 to 33, whereas the bacteria found in group IV were inert and unable to oxidize TMPD. A grouping analysis allowed for the ...

Fig. 1: Cryo-EM structure of thebdoxidase fromM. tuberculosis. aSurface representation of thebdoxidase cryo-EM density map at 2.5 Å resolution. Thebdoxidase consists of a heterodimeric CydAB core dimer The Q-loop of CydA comprises a mostly disordered QNand an ordered QCsegment that are...
We hypothesized that stress-activated protein kinase or c-Jun N-terminal Kinase (SAPK/JNK) is a molecular switch that turns on NETosis in response to increasing concentrations of lipopolysaccharide (LPS)- and Gram-negative bacteria. Here we show that Escherichia coli LPS (0111:B4; 10-25渭g/...
Cytochrome bd-I and Hmp facilitate growth of EC958 in the presence of NO. Gram-negative bacteria can respond to NO-stress in a variety of ways (Fig. 1A). To investigate which systems are important for tolerance to nitrosative stress in UPEC, genes encoding cytochrome bd-I (cydAB),...
This function is conserved throughout evolution, as the enzyme is present from bacteria to man (1). In mammals, the protein also plays an important role in milk secretion (15, 16, 17) and kidney development (18). The function of AOX1 is ill-defined, and the enzyme lacks a recognized ...
Interest in the relationship between gut bacteria and human health has surged in recent years. The gut microbiota is involved in several fundamental physiological functions that maintain metabolic homeostasis, including nutrient processing and digestion, metabolite production, and shaping of the immune syste...
In a preferred embodiment, the pyruvate oxidase mentioned above is produced by a strain of bacteria of the genus Lactobacillus that has pyruvate oxidase activity. In a preferred embodiment, the pyruvate oxidase mentioned above is produced by the strain of Lactobacillus sp. TE-6103. The analytica...
Linlin Sun and Haichun Gao Institute of Microbiology and College of Life Sciences, Zhejiang University, Hangzhou, Zhejiang, China Shewanella species are a group of facultative Gram-negative microorganisms with remarkable respiration abilities that allow the use of a diverse array of terminal electron ac...
While this was expected based on previous studies in other bacteria20,21, the extent of the reduction in oxidase activity in the presence of formate, even at the lower concentrations, was very notable. To further investigate the potential ram- ifications associated with reduction in oxidase ...
