Provided herein are synthetic pathways from Escherichia coli and Vibrio cholerae genes for the production of new, synthetic nonribosomal peptides, and methods and compositions comprising the same. Some aspects of the present disclosure are directed to modified bacterial cells comprising a compressed biosynthetic pathway that comprises (a) biosynthetic genes obtained from one species encoding enzymes active in the bioassembly of a nonribosomal molecule, (b) biosynthetic genes obtained from another species encoding enzymes active in the bioassembly of a nonribosomal molecule that is different from the nonribosomal molecule of (a). In some embodiments, the biosynthetic genes of (a) are Escherichia coli biosynthetic genes and may include entD gene, an entC gene, an entE gene, an entB gene and an entA gene. In some embodiments, the biosynthetic genes of (b) are Vibrio cholera biosynthetic genes and may include a vibH gene and a vibF gene.
本文提供了利用大肠杆菌和霍乱弧菌基因生产新型合成非核糖体肽的合成途径,以及包含这些基因的方法和组合物。本公开的某些方面是针对改良的细菌细胞,该细胞包含压缩的生物合成途径,该途径包括(a)从一个物种获得的生物合成基因,该基因编码在非核糖体分子的生物组装中具有活性的酶;(b)从另一个物种获得的生物合成基因,该基因编码在非核糖体分子的生物组装中具有活性的酶,该非核糖体分子不同于(a)的非核糖体分子。在某些实施方案中,(a)的生物合成基因是大肠杆菌生物合成基因,可包括 entD 基因、entC 基因、entE 基因、entB 基因和 entA 基因。在某些实施方案中,(b)的生物合成基因是霍乱弧菌生物合成基因,可包括 vibH 基因和 vibF 基因。
