腸内菌由来Arylsulfate Sulfotransferaseに関する生化学的研究 [PDF]
, 1995 硫酸抱合反応は，種々の水酸基を有する化合物の解毒の主な経路である。この硫酸化を触媒する酵素としてsulfotransferaseが知られており，この酵素は，arylamine，phenol，steroidやbile acidなどの基質の違いにより分類されている。この酵素は硫酸基を3\u27-phosphoadenosine-5\u27-phosphosulfate(PAPS)からアルコール性あるいはフェノール性水酸基に転移する反応を触媒する。最近，同様な酵素が植物，Flaveriaからも見つかっている ...

Chemistry &Biodiversity, Volume 22, Issue 10, October 2025.Endophytic fungi of P. auritum were evaluated for their ability to produce inhibitors of formation of advanced glycation end products (AGEs). Neopestalotiopsis sp. H2 and Diaporthe sp. H5 extracts were the most active. So, we performed their chemical profiling by untargeted and phenolics‐targeted metabolomic approaches to identify the potential ...
