Antibiotic biosynthesis: Thienamycin and (5R)‐carbapen‐2‐em‐3‐carboxylate (1) are structurally related carbapenem β‐lactam antibiotics that are produced by phylogenetically distant organisms. The biosynthesis of 1 is well understood, thienamycin biosynthesis is not. Here we demonstrate that formation of these carbapenems is functionally and stereochemically identical through only the first two biosynthetic
抗生素生物合成:硫霉素和 (5 R )-carbapen-2-em-3-carboxylate ( 1 ) 是结构相关的碳青霉烯 β-内酰胺抗生素,由系统发育较远的生物体产生。 1的生物合成是众所周知的,但硫霉素的生物合成却不是。在这里,我们证明这些碳青霉烯类的形成仅通过前两个生物合成步骤在功能和立体化学上是相同的。
