Sulfation plays a critical role in the biosynthesis of small molecules, regulatory mechanisms such as hormone signaling, and detoxification processes (phase II enzymes). The sulfation reaction is catalyzed by broad family enzymes known sulfotransferases (SULTs), which have been extensively studied animals due to their medical importance, but also plant key processes. Despite identification some sulfated metabolites fungi, underlying fungal remain largely unknown. To address this knowledge gap, we conducted comprehensive search available genomes, resulting 174 putative SULT genes Ascomycota phylum. Phylogenetic analysis structural modeling revealed that these SULTs belong aryl sulfotransferase family, they are divided into two potential distinct clusters PAPS-dependent within kingdom. from marine fungi isolated deep-sea hydrothermal vents, Hortaea werneckii UBOCC-A-208029 (HwSULT) Aspergillus sydowii UBOCC-A-108050 (AsSULT), were selected representatives each cluster. Recombinant proteins expressed Escherichia coli biochemically characterized. HwSULT demonstrated high versatile activity, while AsSULT appeared more substrate-specific. Here, was used sulfate mycotoxin zearalenone, enhancing its cytotoxicity toward healthy feline intestinal cells.

Long-term alcohol abuse causes psycho-emotional and cognitive impairment, including severe dementia. Oxidative stress is considered one of the main mechanisms in disorders pathophysiology caused by long-term alcoholism. In this regard, search for substances capable correcting mitochondrial dysfunction oxidative that arise as a result prolonged ethanol consumption relevant. Of particular interest complex treatment alcoholic encephalopathy Chinese hyssop ( Lophanthus chinensis ), used Tibetan Mongolian traditional medicine liver diseases, well means improving functional state body metabolism, slowing down aging process.

Abstract Background Scopoletin and umbelliferone belong to coumarins, which are plant specialized metabolites with potent wide biological activities, the accumulation of is induced by various environmental stresses. Coumarins have been detected in species, including medicinal plants model organism Arabidopsis thaliana . In recent years, key role coumarins maintaining iron (Fe) homeostasis has demonstrated, as well their significant impact on rhizosphere microbiome through exudates secreted into soil environment. Several mechanisms underlying these processes require clarification. Previously, we demonstrated that an excellent for studying genetic variation molecular basis coumarin plants. Results Here, targeted metabolic profiling gene expression analysis, gene-metabolite network scopoletin was examined more detail selected accessions (Col-0, Est-1, Tsu-1) undergoing different culture conditions characterized content. The highest roots grown vitro liquid culture. 10 phenylpropanoid genes ( 4CL1 , 4CL2 4CL3 CCoAOMT1 C3’H HCT F6’H1 F6’H2 CCR1 CCR2 ) assessed qPCR three backgrounds, cultured soil, two types tissues (leaves roots). We not only expected variability among accessions, but also found interesting polymorphisms coding sequences silico analysis resequencing. Conclusions To best our knowledge, this first study comparing simple phenylpropanoid-related cultures. large variations content genetically determined, tissue dependent. It particularly important considering growing media a widely used technology provides amount root suitable metabolomics. Research differential related will be useful future studies aimed at better understanding physiological surrounding environments.
