The present application relates to compositions comprising selenium (e.g., selenium enriched yeast and selenium containing compounds obtained or derived therefrom) and methods of using the same to treat and inhibit obesity, diabetes and related conditions. In particular, the present application provides compositions comprising selenium enriched yeast (e.g., selenium enriched yeast comprising 2% or less inorganic selenium), selenium containing compounds present therein and/or derived therefrom, and methods of using the same to enhance mitochondrial activity and function (e.g., in skeletal muscle and liver) in a subject (e.g., as a therapeutic and/or prophylactic treatment for diabetes, obesity and related conditions).

the chemoenzymaticsynthesis of 29 non‐native SAM analogues. As a proof of concept for the feasibility of natural product “alkylrandomization”, a small set of differentially‐alkylated indolocarbazole analogues was generated by using a coupled hMAT2–RebM system (RebM is the sugar C4′‐O‐methyltransferase that is involved in rebeccamycin biosynthesis). The ability to couple SAM synthesis and utilization
据报道,用于合成S-腺苷-L-甲硫氨酸 (SAM) 类似物的化学酶平台与下游 SAM 利用酶兼容。合成了 44 种非天然 S/Se 烷基化 Met 类似物,并将其用于探测五种不同的蛋氨酸腺苷转移酶 (MAT) 的底物特异性。人类 MAT II 是所分析的 MAT 中最受允许的之一,并且能够化学酶合成 29 种非天然 SAM 类似物。作为天然产物“烷基随机化”可行性的概念证明,通过使用耦合的 hMAT2-RebM 系统(RebM 是参与瑞贝卡霉素的糖 C4'- O-甲基转移酶)生成了一小组差异烷基化吲哚并咔唑类似物。生物合成)。在单个容器中耦合 SAM 合成和利用的能力避免了与 SAM 类似物快速分解相关的问题,从而为进一步研究各种 SAM 利用酶打开了大门。

The present disclosure relates to the synthesis of non-natural analogs of S-adenosyl-L-methionine (SAM) and/or of Se-adenosyl-L-methionine (SeAM) by reacting a methionine analog and adenosine triphosphate (ATP) in the presence of at least one methionine adenosyltransferase (MAT), and to use thereof with downstream SAM and/or SeAM utilizing enzymes. The non-natural analogs of SAM and/or SeAM have the general formula:
where X is S or Se, and R1 is an alkyl group.
