Scannell TI - Precision Discovery of Novel Inhibitors of Cancer Target HsMetAP1 from Vast Metagenomic Diversity AID - 10.1101/2022.06.11.495772 DP - 2022 Jan 01 TA - bioRxiv PG - 2022.06.11.495772 4099 - http://biorxiv.org/content/early/2022/08/30/2022.06.11.495772.short 4100 - http://biorxiv.org/content/early/2022/08/30/2022.06.11.495772.full AB - Microbial natural products have long been a rich source of human therapeutics. While the chemical diversity encoded in the genomes of microbes is large, this modality has waned as fermentation-based discovery methods have suffered from rediscovery, inefficient scaling, and incompatibility with target-based discovery paradigms. Here, we leverage a metagenomic partitioning strategy to sequence soil microbiomes at unprecedented depth and quality. We then couple these data with target-focused, in silico search strategies and synthetic biology to discover multiple novel natural product inhibitors of human methionine aminopeptidase-1 (HsMetAP1), a validated oncology target. For one of these, metapeptin B, we demonstrate sub-micromolar potency, strong selectivity for HsMetAP1 over HsMetAP2 and elucidate structure-activity relationships. Our approach overcomes challenges of traditional natural product methods, accesses vast, untapped chemical diversity in uncultured microbes, and demonstrates computationally-enabled precision mining of modulators of human proteins.Competing Interest StatementMultiple authors are/were employees of Zymergen, Inc.
