摘要
Natural product peptide-based proteasome inhibitors show great potential as anticancer drugs. Here we have cloned the biosynthetic gene cluster of a potent proteasome inhibitorglidobactin from Burkholderia DSM7029and successfully detected glidobactins/luminmycins in E. coli Nissle. We have also improved the yield of glidobactin A tenfold by promoter change in a heterologous host. In addition, two new biosynthetic intermediates were identified by comparative MS/MS fragmentation analysis. Identification of acyclic luminmycin E implies substrate specificity of the TE domain for cyclization. The establishment of a heterologous expression system for syrbactins provided the basis for the generation of new syrbactins as proteasome inhibitors by molecular engineering, but the TE domain's specificity cannot be ignored.
