Out of 24 fungal strains tested for their ability to transform 8-prenylnaringenin, Syncephalastrum racemosum was found to convert this phytoestrogen to a sulfate derivative. The conjugation with sulfuric acid observed in this study is paralleled in mammals indicating that microbes can be used to mimic mammalian metabolism.
Tyrosine sulfation, a well-characterized post-translation modification in eukaryotes, has not previously been reported in prokaryotes. Here, we demonstrate that the RaxST protein from the Gram-negative bacterium, Xanthomonas oryzae pv. oryzae, is a tyrosine sulfotransferase. We used a newly developed sulfotransferase assay and ultraviolet photodissociation mass spectrometry to demonstrate that ...
Abstract Background It is widely accepted that high-fat diet (HFD) has been considered as one of the risk factors inflammatory bowel disease(IBD), while mechanism little known. We aimed to examined whether dietary high fat promotes colonic inflammation through modulating gut microbial tryptophan metabolites. Methods The C57BL/6 female mice were fed with chow (12kcal% fat) or HFD (60kcal% for 2 ...
The process of sulfation products neutralization in the production surfactants is not basic, but at this stage positive effects obtained organic matter with sulfur trioxide gas are fixed. To preserve degree obtained, it necessary to carry out under conditions precluding occurrence hydrolysis an acidic medium. reaction takes place a high heat release about 40 kJ / mol. Analysis literature data s...
