Discovery of MRSA active antibiotics using primary sequence from the human microbiome

October 17th, 2016 by John Chu

Nature Chemical Biology 12, 1004 (2016). doi:10.1038/nchembio.2207

Authors: John Chu, Xavier Vila-Farres, Daigo Inoyama, Melinda Ternei, Louis J Cohen, Emma A Gordon, Boojala Vijay B Reddy, Zachary Charlop-Powers, Henry A Zebroski, Ricardo Gallardo-Macias, Mark Jaskowski, Shruthi Satish, Steven Park, David S Perlin, Joel S Freundlich & Sean F Brady

Here we present a natural product discovery approach, whereby structures are bioinformatically predicted from primary sequence and produced by chemical synthesis (synthetic-bioinformatic natural products, syn-BNPs), circumventing the need for bacterial culture and gene expression. When we applied the approach to nonribosomal peptide synthetase gene clusters from human-associated bacteria, we identified the humimycins. These antibiotics inhibit lipid II flippase and potentiate β-lactam activity against methicillin-resistant Staphylococcus aureus in mice, potentially providing a new treatment regimen.

Structural basis of nonribosomal peptide macrocyclization in fungi

October 17th, 2016 by Jinru Zhang

Nature Chemical Biology 12, 1001 (2016). doi:10.1038/nchembio.2202

Authors: Jinru Zhang, Nicholas Liu, Ralph A Cacho, Zhou Gong, Zhu Liu, Wenming Qin, Chun Tang, Yi Tang & Jiahai Zhou

Nonribosomal peptide synthetases (NRPSs) in fungi biosynthesize important pharmaceutical compounds, including penicillin, cyclosporine and echinocandin. To understand the fungal strategy of forging the macrocyclic peptide linkage, we determined the crystal structures of the terminal condensation-like (CT) domain and the holo thiolation (T)-CT complex of Penicillium aethiopicum TqaA. The first, to our knowledge, structural depiction of the terminal module in a fungal NRPS provides a molecular blueprint for generating new macrocyclic peptide natural products.
