This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. (1R,6R)-2-Succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate (SHCHC) synthase, also called MenD, participates in the menaquinone (Vitamin K2) biosynthetic pathway. The enzyme is a part of the superfamily of ThDP-dependent enzymes, however it is the only enzyme known to catalyze a Stetter-like 1,4-addition of a ThDP adduct to the alpha-carbon of an unsaturated carboxylate. The crystal structure of this enzyme will be important for clarifying the mechanism of this important enzyme.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。 (1R,6R)-2-琥珀酰-6-羟基-2,4-环己二烯-1-羧酸酯 (SCHHC) 合酶，也称为 MenD，参与甲基萘醌（维生素 K2）生物合成途径。该酶是 ThDP 依赖性酶超家族的一部分，但它是已知唯一能够催化 ThDP 加合物与不饱和羧酸酯的 α-碳发生类似 Stetter 1,4-加成反应的酶。这种酶的晶体结构对于阐明这种重要酶的机制非常重要。
