involved in key cellular and physiological processes. Isotopically labeled flavin is a powerful tool for studying the structure and mechanism of flavoenzyme-catalyzed reactions by a variety of techniques, including NMR, IR, Raman, and mass spectrometry. In this report, we describe the preparation of labeled FMN isotopologues enriched with 15N and 13C isotopes at various sites in the pyrazine and pyrimidine
黄素单核苷酸(FMN)是参与关键细胞和生理过程的众多蛋白质的辅酶。同位素标记的黄素是通过各种技术(包括NMR,IR,拉曼和质谱法)研究黄素酶催化反应的结构和机制的强大工具。在这份报告中,我们描述了通过五步化学酶促合成方法,从易得的前体中制备富集15 N和13 C同位素的,富含15 N和13 C同位素的标记的FMN同位素,辅酶的异四恶嗪核心的吡嗪和嘧啶环。
