Whereas some target-E3 interfaces exhibit the capacity to accommodate structurally diverse degraders, the extent of this adaptability across molecular glue targets remains unclear. We recently identified (S)-ACE-OH as a molecular glue degrader that recruits the E3 ubiquitin ligase TRIM21 to the nuclear pore complex by recognizing NUP98, thereby inducing the degradation of nuclear pore proteins. Here, we analyzed public compound toxicity data across a large collection of cell lines and identified two additional molecular glue degraders, PRLX 93936 and BMS-214662, which engage the TRIM21-NUP98 interface to induce selective degradation of nuclear pore proteins. Additionally, we confirmed that HGC652, another TRIM21-dependent molecular glue degrader, also binds at this interface. Together with our previously characterized degrader (S)-ACE-OH, these findings demonstrate that the TRIM21-NUP98 interface can accommodate structurally diverse molecular glue degraders.","PeriodicalId":11,"journal":{"name":"ACS Chemical Biology","volume":"20 4","pages":"953–959 953–959"},"PeriodicalIF":3.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A substantial proportion of LAPs have been identified in mesophilic microorganisms, including actinomycetes. In this study, we report the biosynthetic reconstitution and characterization of parageocin I, a novel thiazole-rich LAP derived from the thermophilic bacterium Parageobacillus caldoxylosilyticus KH1-5 which exhibits optimal growth around 60 °C. The biosynthetic gene cluster (pgc) consists of four genes: pgcA, pgcB, pgcC, and pgcD, encoding the precursor peptide, dehydrogenase, YcaO family cyclodehydratase, and biosynthetic scaffold protein, respectively. The precursor peptide PgcA possesses 13 Cys and 2 Ser residues, with regularly repeated sequences interspaced between Cys residues. We first reconstituted the biosynthesis heterologously in Escherichia coli. Mass spectrometry analysis of the synthesized peptide, coupled with mutational analyses of the modified PgcA, revealed that the final product, designated as parageocin I, harbors 13 thiazole rings derived from the cyclization of Cys residues, while Ser residues remain intact. Furthermore, mutational studies of PgcA revealed three key principles governing heterocyclization by PgcC: (i) Cys is acceptable, but Ser and Thr are not; (ii) the presence of an acidic amino acid preceding Cys is not permissible; and (iii) a minimum of two amino acids must separate Cys residues. In addition, we successfully reconstituted the biosynthesis in vitro using the purified recombinant enzymes. This is the first report of LAP biosynthesis in thermophilic Bacillaceae, thereby expanding our understanding of not only LAPs but also secondary metabolism in thermophiles.","PeriodicalId":11,"journal":{"name":"ACS Chemical Biology","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, diversifying these compounds and their corresponding downstream products hinges on broadening the promiscuity of CoA ligases that produce them or using additional enzymes to functionalize them. Here, the inherent promiscuity of an acyl-CoA ligase from Pseudomonas chlororaphis was probed with carboxylic acids of varying sizes and functionality. The enzyme was engineered to improve its activity with a diverse panel of acyl-CoA thioesters, including halogenated and oxidized acids, that can be used in downstream biosynthetic production strategies. To demonstrate the utility of the engineered enzyme, a subset of the substrates was leveraged for the complete in situ biosynthesis of a small panel of pyrones via a portion of the archetypal polyketide synthase (PKS), 6-deoxyerythronolide B synthase (DEBS). This approach supports probing the promiscuity of polyketide biosynthesis and the diversification of natural product scaffolds.","PeriodicalId":11,"journal":{"name":"ACS Chemical Biology","volume":"20 4","pages":"930–941 930–941"},"PeriodicalIF":3.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
