title: In vivo biocombinatorial synthesis of lipopeptides by COM domain-mediated reprogramming of the surfactin biosynthetic complex.
abstract: The intermolecular communication within NRPS complexes relies on the coordinated interplay of donor and acceptor communication-mediating (COM) domains. In this study, the potential of COM domains was exploited in vivo by establishing a system for the true biocombinatorial synthesis of lipopeptides via directed reprogramming of a natural NRP biosynthetic assembly line (i.e., surfactin). By means of COM domain swapping, these experiments verified the decisive role of COM domains for the control of protein-protein interactions between NRPSs, demonstrated the functionality of COM domain pairs even in the context of a heterologous host and NRPS system, and allowed for the intended skipping of a biosynthetic enzyme within a multienzymatic biosynthetic complex. Ultimately, abrogation of the selectivity barrier provided by COM domains afforded the successful simultaneous, biocombinatorial synthesis of distinct lipopeptide products.
