To improve genome engineering methodologies in <i>B. subtilis</i>, we revisited the potential of MAD7 for gene modification and expression interference. A key challenge in these endeavors is the limited transformation efficiency. To overcome this, we developed an efficient transformation protocol using strains overexpressing competence genes. Our results showed that although MAD7 together with a <i>B. subtilis</i> chromosome-targeting gRNA is lethal, enabling robust counterselection, we successfully engineered a strain carrying the MAD7-gRNA machinery in a reversibly inactivated state, marking a significant advance in the field. We demonstrated that both MAD7 and its catalytically inactive variant (dMAD7) can be conditionally regulated by inactivation at elevated temperatures. In addition, the MAD7-gRNA complex is effective for multiplex genome editing, allowing for the simultaneous deletion, mutation, or insertion of up to four loci, and enabling the combination of gene deletion, gene insertion, and point mutations. Furthermore, we established a strategy that achieves the simultaneous removal of MAD7 and the gRNA along with the desired genome edits. Altogether, this comprehensive study underscores the versatility of MAD7 for complex, scarless genome engineering and lays a strong foundation for further advancing genetic manipulation in <i>B. subtilis</i>.</p>","PeriodicalId":26,"journal":{"name":"ACS Synthetic Biology","volume":"14 8","pages":"3142–3153"},"PeriodicalIF":3.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740620","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}

By timely administering molecular regulators (e.g., transcription factors, RNAs, or small molecules) in a process that mimics in vivo embryonic development, stem cell differentiation can be guided toward a specific cell fate. However, scaling up these therapies is extremely challenging because such differentiation strategies often result in mixed cellular populations. While synthetic biology approaches have been proposed to increase the yield of desired cell types, designing gene circuits that effectively redirect cell fate decisions requires mechanistic insight into the dynamics of the endogenous regulatory networks that govern this type of decision-making. In this work, we present a biomolecular adaptive controller designed to favor a specific cell fate. The controller, whose topology is akin to that of an Incoherent Feedforward Loop (IFFL), requires minimal knowledge of the endogenous network as it exhibits adaptive, non-reference-based behavior. The synthetic circuit operates through a sequestration mechanism and a delay introduced by an intermediate species, producing an output that asymptotically approximates a discrete temporal derivative of its input if the sequestration rate is sufficiently fast. Allowing the controller to actuate over a target species involved in the decision-making process creates a tunable synthetic bias that favors the production of the desired species with minimal alteration to the overall equilibrium landscape of the endogenous network. Through theoretical and computational analysis, we provide design guidelines for the controller’s optimal operation, evaluate its performance under parametric perturbations, and extend its applicability to various examples of common multistable systems in biology.</p>","PeriodicalId":26,"journal":{"name":"ACS Synthetic Biology","volume":"14 8","pages":"3163–3176"},"PeriodicalIF":3.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acssynbio.5c00299","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While prokaryotic bacteria synthesize terpenoids via the methylerythritol-4-phosphate (MEP) pathway, fungi utilize the mevalonate (MVA) pathway. The MVA pathway has been widely employed for efficient terpenoid production in bacteria such as <i>Escherichia coli</i>, but the MEP pathway performs poorly for biosynthesis in yeast. In this study, we constructed a compartmentalized MEP pathway to enhance monoterpenoid production in <i>Saccharomyces cerevisiae</i>. By introducing a geraniol synthase, we initially achieved the production of geraniol from glucose. Further effective incorporation of a cytosolic MEP pathway with nine enzymes increased geraniol production by 174.5%. However, this also significantly inhibited cell growth. Overexpression analysis revealed that flavodoxin and flavodoxin reductase were major contributors to growth inhibition, which could also be a factor limiting the application of the MEP pathway. To address these issues, we employed peroxisomal compartmentalization to isolate the MEP pathway from cytosolic metabolism. This strategy alleviated growth inhibition and improved geraniol production by 93.18% compared to that of cytosolic expression. Through additional metabolic engineering, we optimized peroxisomal geraniol production, achieving a yield of 30.64 mg/L.

To identify potential effectors for synergistic activation in bacteria, we systematically characterized bacterial activator proteins with a set of engineered synthetic promoters. We found that optimal target sites for different activators could vary by up to 200 bases in the region upstream of the transcription start site (TSS). These optimal target sites qualitatively matched previous reports for each activator, but the precise targeting rules varied between different promoters. By characterizing targeting rules in the same promoter context, we were able to test activator combinations with each effector positioned at its optimal target site.

In this work, we demonstrate that multiple cell-free expressed enzymes can be co-immobilized in biocompatible hydrogels made from poly(ethylene glycol) diacrylate (PEGDA) with added glycerol for enhanced gel integrity. Using small-angle X-ray scattering (SAXS), we show that the mesh size of PEGDA-glycerol hydrogels is comparable to the globular sizes of many proteins and enzymes, which could be used for protein entrapment. We found that the combination between entrapment and chemical ligation of the enzymes was effective to retain proteins. By employing a method for direct fluorescence measurement from hydrogels, we found that proteins can be retained in PEGDA-glycerol for at least a week. By separating the cell-free enzyme expression from the immobilization step, we successfully fabricated enzyme-laden hydrogels with three heterologous cell-free enzymes for the bioconversion of pyruvic acid to malic acid, an industrially valuable and versatile precursor chemical. Both heterologous and endogenous enzymes from the lysate remain functional in photo-cross-linked hydrogels and can be reused for multiple biocatalytic cycles. Moreover, we also found that the immobilized enzymes exhibit up to 1.6-fold higher activity and 2-fold longer lifetimes than free enzymes in liquid reactions.
