A terpene synthase from the marine bacterium Streptomyces xinghaiensis has been characterised, including a full structure elucidation of its products from various substrates and an in‐depth investigation of the enzyme mechanism by isotope labelling experiments, metal cofactor variations, and mutation experiments. The results revealed an interesting dependency of Mn2+ catalysis on the presence of Asp‐217
已经表征了来自海洋细菌星海链霉菌的萜烯合酶,包括从各种底物上对其产物的完整结构阐明,以及通过同位素标记实验,金属辅因子变异和突变实验对酶机理的深入研究。结果表明,Mn 2+催化对Asp-217的存在有令人感兴趣的依赖性,Asp-217是大多数其他细菌萜烯合酶中被高度保守的Glu占据的残基。
