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.</p><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}

After profiling the <i>N</i>-glycosylation and phosphorylation patterns, we found that these two types of PTMs differentially shape the intrinsic signaling bias of GPR52. While N-terminal <i>N</i>-glycosylation promotes constitutive G<sub>s</sub> 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 <i>N</i>-glycosylation and phosphorylation in modulating GPR52-dependent accumulation of the huntingtin protein in brain striatal cells.

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.</p><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 <span>l</span>-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.
