Here we report the biosynthesis and characterization of a group of biopolymers, poly(ester amide)s (PEAs), in Escherichia coli. PEAs are biosynthesized by constructing a new-to-nature amino acid polymerization pathway, comprising amino acid activation by β-alanine CoA transferase and subsequent polymerization of amino acyl-CoA by polyhydroxyalkanoate synthase. The engineered E. coli strains harboring this pathway are capable of biosynthesizing various PEAs, each incorporating different amino acid monomers in varying fractions. Examination of the physical, thermal and mechanical properties reveals a dependence of molecular weight on the type of polyhydroxyalkanoate synthase, a decrease in melting temperature and crystallinity as the 3-aminopropionate monomer fraction increases and enhanced elongation at break compared to its polyester analog. The engineered bacterial system will prove beneficial for the biobased production of various PEAs using renewable resources.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"14 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we divide the lignan biosynthetic pathway across a synthetic yeast consortium with obligated mutualism and use ferulic acid as a metabolic bridge. This cooperative system successfully overcomes the metabolic promiscuity and synthesizes the common precursor, coniferyl alcohol. Furthermore, combined with systematic engineering strategies, we achieve the de novo synthesis of key lignan skeletons, pinoresinol and lariciresinol, and verify the scalability of the consortium by synthesizing complex lignans, including antiviral lariciresinol diglucoside. These results provide a starting engineering platform for the heterologous synthesis of lignans. In particular, the study illustrates that the yeast consortium with obligate mutualism is a promising strategy that mimics the metabolic division of labor among multiple plant cells, thereby improving the biosynthesis of long pathways and complex natural products.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"16 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143635298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study of GPR52, an orphan GPCR with exceedingly high constitutive G-protein activity that is emerging as a neurotherapeutic target, we discovered its disproportionately low arrestin recruitment activity. After profiling the N-glycosylation and phosphorylation patterns, we found that these two types of PTMs differentially shape the intrinsic signaling bias of GPR52. While N-terminal N-glycosylation promotes constitutive Gs signaling possibly through favoring the self-activating conformation, phosphorylation in helix 8, to our great surprise, suppresses arrestin recruitment and attenuates receptor internalization. In addition, we uncovered the counteracting roles of N-glycosylation and phosphorylation in modulating GPR52-dependent accumulation of the huntingtin protein in brain striatal cells. Our study provides new insights into the regulation of intrinsic signaling bias and cellular function of an orphan GPCR through distinct PTMs in different motifs.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"23 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By engineering synthetic anchor proteins capable of tethering various genetically encoded condensate structures toward different cellular compartments or gene products of interest, inducible regulation of transcriptional and translational activities was achieved at different endogenous and episomal loci using the same sets of anchor proteins and synthetic solid-state condensates. Using such a holistic condensate-based strategy, we not only achieved regulation performances comparing favorably to state-of-the-art strategies described for CRISPR–Cas9 activity and transcriptional silencing but further showed that chemically inducible retention of mRNA molecules into engineered condensate structures within the nucleus can become a remarkably efficient alternative for translational regulation.<figure></figure>","PeriodicalId":18832,"journal":{"name":"Nature chemical biology","volume":"88 1","pages":""},"PeriodicalIF":14.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The molecular mechanism by which dimeric family C GPCR members recruit arrestins remains elusive. Here we report two structures of metabotropic glutamate receptor subtype 3 (mGlu3) coupled to βarr1, with stoichiometries of 2:1 and 2:2. The l-glutamate-bound mGlu3 dimer adopts an inactive state, with both Venus flytrap domains closed, engaging βarr1 either asymmetrically or symmetrically. The transmembrane domain of the mGlu3 protomer interacts with βarr1 through a binding pocket formed by three intracellular loops and an ordered C-terminal region. Three phosphorylation sites (pS857, pS859 and pT860) on the C-terminal tail of mGlu3 engage the N domain of βarr1. βarr1 stabilizes mGlu3 in an inactive conformation, characterized by a TM3/TM4–TM3/TM4 dimeric interface, previously observed in the negative allosteric modulator-bound structure of mGlu3.
