Lassomycin and lariatin lasso peptides as suitable antibiotics for combating mycobacterial infections: current state of biosynthesis and perspectives for production.
Lasso peptides are ribosomally synthesized and post-translationally modified natural products with a characteristic slipknot-like structure, which confers these peptides remarkable stability and diverse pharmacologically relevant bioactivities. Among all the reported lasso peptides, lassomycin and lariatins are unique lasso peptides that exhibit noticeable anti-tuberculosis (TB) activity. Due to the unique threaded structure and the unusual bactericidal mechanism toward Mycobacterium tuberculosis, these peptides have drawn considerable interest, not only in the field of total synthesis but also in several other fields including biosynthesis, bioengineering, and structure-activity studies. During the past few years, significant progress has been made in understanding the biosynthetic mechanism of these intriguing compounds, which has provided a solid foundation for future work. This review highlights recent achievements in the discovery, structure elucidation, biological activity, and the unique anti-TB mechanism of lasso peptides. Moreover, the discovery of their biosynthetic pathway has laid the foundation for combinatorial biosynthesis of their analogs, which provides new perspectives for the production of novel anti-TB lasso peptides.

Crystal structure of the N-terminal domain of MtClpC1 in complex with the anti-mycobacterial natural peptide Lassomycin.
Antibiotics form our frontline therapy against disease-causing bacteria. Unfortunately, antibiotic resistance is becoming more common, threatening a future where these medications can no longer cure infections. Furthermore, the emergence of multidrug-resistant (MDR), totally drug-resistant (TDR), and extensively drug-resistant (XDR) tuberculosis has increased the urgency of discovering new therapeutic leads with unique modes of action. Some natural peptides derived from actinomycetes, such as Cyclomarin A, Lassomycin, Rufomycin I, and Ecumicin, have potent and specific bactericidal activity against Mycobacterium tuberculosis, with the specificity owing to the fact that these peptides target the ClpC1 ATPase, an essential enzyme in mycobacteria, and inhibit/activate the proteolytic activity of the ClpC1/P1/P2 complex that participates in protein homeostasis. Here, we report the high-resolution crystal structure of the N-terminal domain of ClpC1 (ClpC1 NTD) in complex with Lassomycin, showing the specific binding mode of Lassomycin. In addition, the work also compares the Lassomycin complex structure with the previously known structures of ClpC1 NTD in complex with other natural peptides such as Cyclomarin A, Rufomycin I, and Ecumicin.
