Abstract
Monoterpene indole alkaloids (MIAs) are a group of plant-derived natural products with high-value medicinal properties. However, their availability for clinical application is limited due to challenges in plant extraction. Microbial production has emerged as a promising strategy to meet the clinical demands for MIAs. The biosynthetic pathway of cis-trans nepetalactol, which serves as the universal iridoid scaffold for all MIAs, has been successfully identified and reconstituted. However, bottlenecks and challenges remain to construct a high-yielding platform strain for cis-trans nepetalactol production, which is vital for subsequent MIAs biosynthesis. In the present study, we focused on engineering of Pichia pastoris cell factories to enhance the production of geraniol, 8-hydroxygeraniol, and cis-trans nepetalactol. By targeting the biosynthetic pathway from acetyl-CoA to geraniol in both peroxisomes and cytoplasm, we achieved comparable geraniol titers in both compartments. Through protein engineering, we found that either G8H or CPR truncation increased the production of 8-hydroxygeraniol, with a 47.8-fold and 14.0-fold increase in the peroxisomal and cytosolic pathway strain, respectively. Furthermore, through a combination of dynamical control of ERG20, precursor and cofactor supply engineering, diploid engineering, and dual subcellular compartmentalization engineering, we achieved the highest ever reported production of cis-trans nepetalactol, with a titer of 4429.4 mg/L using fed-batch fermentation in a 5-L bioreactor. We anticipate our systematic metabolic engineering strategies to facilitate the development of P. pastoris cell factories for sustainable production of MIAs and other plant natural products.

Abstract
Synthetic biology dictates the data-driven engineering of biocatalysis, cellular functions, and organism behavior. Integral to synthetic biology is the aspiration to efficiently find, access, interoperate, and reuse high-quality data on genotype-phenotype relationships of native and engineered biosystems under FAIR principles, and from this facilitate forward-engineering strategies. However, biology is complex at the regulatory level, and noisy at the operational level, thus necessitating systematic and diligent data handling at all levels of the design, build, and test phases in order to maximize learning in the iterative design-build-test-learn engineering cycle. To enable user-friendly simulation, organization, and guidance for the engineering of biosystems, we have developed an open-source python-based computer-aided design and analysis platform operating under a literate programming user-interface hosted on Github. The platform is called teemi and is fully compliant with FAIR principles. In this study we apply teemi for i) designing and simulating bioengineering, ii) integrating and analyzing multivariate datasets, and iii) machine-learning for predictive engineering of metabolic pathway designs for production of a key precursor to medicinal alkaloids in yeast. The teemi platform is publicly available at PyPi and GitHub.

Liu H, Liang S, Zhu M, Shi W, Xu C, Wei W, Zhan R, Ma D. A fused hybrid enzyme of 8-hydroxygeraniol oxidoreductase (8HGO) from Gardenia jasminoides and iridoid synthase (ISY) from Catharanthus roseus significantly enhances nepetalactol and iridoid production. PLANTA 2024; 259:62. [PMID: 38319463 DOI: 10.1007/s00425-023-04287-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 11/12/2023] [Indexed: 02/07/2024]
Abstract
MAIN CONCLUSION The operation of 8HGO-ISY fusion enzymes can increase nepetalactol flux to iridoid biosynthesis, and the Gj8HGO-CrISY expression in Gardenia jasminoides indicates that seco-iridoids and closed-ring iridoids share a nepetalactol pool. Nepetalactol is a common precursor of (seco)iridoids and their derivatives, which are a group of noncanonical monoterpenes. Functional characterization of an 8HGO (8-hydroxygeraniol oxidoreductase) from Catharanthus roseus, a seco-iridoids producing plant, has been reported; however, the 8HGO from G. jasminoides with plenty of closed-ring iridoids remains uninvestigated. In this work, a Gj8HGO was cloned and biochemically characterized. In addition, the relatively low production of nepetalactol in plants and engineered microbial host is likely to be attributed to the fact that Cr8HGO and CrISY (iridoid synthase) are substrate-promiscuous enzymes catalyzing unexpected substrates to the undesired products. Herein, a bifunctional enzyme consisting of an 8HGO fused to an ISY was designed for the proximity to the substrate and recycling of NADP+ and NADPH cofactor to reduce the undesired intermediate in the synthesis of nepetalactol. Of four fusion enzymes (i.e., Gj8HGO-GjISY, Gj8HGO-GjISY2, Gj8HGO-GjISY4, and Gj8HGO-CrISY), interestingly, only the last one can enable cascade reaction to form cis-trans-nepetalactol. Furthermore, we establish a reliable Agrobacterium-mediated transformation system. The expression of Gj8HGO-CrISY in G. jasminoides led to a significant enhancement of nepetalactol production, about 19-fold higher than that in wild-type plants, which further resulted in the twofold to fivefold increase of total iridoids and representative iridoid such as geniposide, indicating that seco-iridoids in C. roseus and closed-ring iridoids in G. jasminoides share a nepetalactol pool. All results suggest that 8HGO and ISY can be manipulated to maximize metabolic flux for nepetalactol and iridoid production.

Abstract
Statins are lipid-lowering drugs that selectively inhibit 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, effectively reducing cholesterol synthesis. With improved nutritional conditions, the demand for statins is increasing in the global market. The use of microbial cell factories for statin biosynthesis has become advantageous due to the rapid advancements in biotechnology. These approaches offer simple operation and easy separation of products. This review provides an overview the strategies for statins production via microbial cell factories, including both traditional fermentation culture (non-genetic) and modern synthetic biology manufacture (genetic). Firstly, the complex fermentation parameters and process control technology on submerged fermentation (SmF) and solid-state fermentation (SSF) are introduced in detail. The potential use of recoverable agricultural wastes/(biomass) as a fermentation substrate in SSF for statin production is emphasized. Additionally, metabolic engineering strategies for constructing robust engineering strains and directed evolution are also discussed. The review highlights the potential and challenges of using microbial cell factories for statin production, and aims to promote greener production modes for statins.

Abstract
Microbial production of monoterpenoid indole alkaloids (MIAs) provides a sustainable and eco-friendly means to obtain compounds with high pharmaceutical values. However, efficient biosynthesis of MIAs in heterologous microorganisms is hindered due to low supply of key precursors such as geraniol and its derivative 8-hydroxygeraniol catalyzed by geraniol 8-hydroxylase (G8H). In this study, we developed a facile evolution platform to screen strains with improved yield of geraniol by using the SCRaMbLE system embedded in the Sc2.0 synthetic yeast and confirmed the causal role of relevant genomic targets. Through genome mining, we identified several G8H enzymes that perform much better than the commonly used CrG8H for 8-hydroxygeraniol production in vivo. We further showed that the N-terminus of these G8H enzymes plays an important role in cellular activity by swapping experiments. Finally, the combination of the engineered chassis, optimized biosynthesis pathway, and utilization of G8H led to the final strain with more than 30-fold improvement in producing 8-hydroxygeraniol compared with the starting strain. Overall, this study will provide insights into the construction and optimization of yeast cells for efficient biosynthesis of 8-hydroxygeraniol and its derivatives.

Abstract
Secondary natural products (NPs) are a rich source for drug discovery. However, the low abundance of NPs makes their extraction from nature inefficient, while chemical synthesis is challenging and unsustainable. Saccharomyces cerevisiae and Pichia pastoris are excellent manufacturing systems for the production of NPs. This Perspective discusses a comprehensive platform for sustainable production of NPs in the two yeasts through system-associated optimization at four levels: genetics, temporal controllers, productivity screening, and scalability. Additionally, it is pointed out critical metabolic building blocks in NP bioengineering can be identified through connecting multilevel data of the optimized system using deep learning.

Abstract
8-Hydroxygeraniol, an important component of insect sex pheromones and defensive secretions, can be used as a potential biological insect repellent in agriculture. Microbial production provides sustainable and green means to efficiently gain 8-hydroxygeraniol. The conversion of geraniol to 8-hydroxygeraniol by P450 geraniol-8-hydroxylase (G8H) was regarded as the bottleneck for 8-hydroxygeraniol production. Herein, an integrated strategy consisting of the fitness between G8H and cytochrome P450 reductase (CPR), endoplasmic reticulum (ER) engineering, and reduced nicotinamide adenine dinucleotide phosphate (NADPH) supply is implemented to enhance the production of 8-hydroxygeraniol in Saccharomyces cerevisiae. The titer of 8-hydroxygeraniol was gradually increased by 2.1-fold (up to 158.1 mg/L). Moreover, dehydrogenase ADH6 and reductase ARI1 responsible for the reduction of 8-hydroxygeraniol toward shunt products were also deleted, elevating 8-hydroxygeraniol production to 238.9 mg/L at the shake flask level. Consequently, more than 1.0 g/L 8-hydroxygeraniol in S. cerevisiae was achieved in 5.0 L fed-batch fermentation by a carbon restriction strategy, which was the highest-reported titer in microbes so far. Our work not only provides a sustainable way for de novo biosynthesis of 8-hydroxygeraniol but also sets a good reference in P450 engineering in microbes.

Abstract
![]()
As redesigning organisms using engineering principles
is one of
the purposes of synthetic biology (SynBio), the standardization of
experimental methods and DNA parts is becoming increasingly a necessity.
The synthetic biology community focusing on the engineering of Saccharomyces cerevisiae has been in the foreground in this
area, conceiving several well-characterized SynBio toolkits widely
adopted by the community. In this review, the molecular methods and
toolkits developed for S. cerevisiae are discussed
in terms of their contributions to the required standardization efforts.
In addition, the toolkits designed for emerging nonconventional yeast
species including Yarrowia lipolytica, Komagataella
phaffii, and Kluyveromyces marxianus are
also reviewed. Without a doubt, the characterized DNA parts combined
with the standardized assembly strategies highlighted in these toolkits
have greatly contributed to the rapid development of many metabolic
engineering and diagnostics applications among others. Despite the
growing capacity in deploying synthetic biology for common yeast genome
engineering works, the yeast community has a long journey to go to
exploit it in more sophisticated and delicate applications like bioautomation.

Abstract
Antibiotic resistance is a growing global health threat, demanding urgent responses. Tetracyclines, a widely used antibiotic class, are increasingly succumbing to antibiotic resistance; generating novel analogues is therefore a top priority for public health. Fungal tetracyclines provide structural and enzymatic diversity for novel tetracycline analogue production in tractable heterologous hosts, like yeasts, to combat antibiotic-resistant pathogens. Here, we successfully engineered Saccharomyces cerevisiae (baker's yeast) and Saccharomyces boulardii (probiotic yeast) to produce the nonantibiotic fungal anhydrotetracycline, TAN-1612, in synthetic defined media─necessary for clean purifications─through heterologously expressing TAN-1612 genes mined from the fungus, Aspergillus niger ATCC 1015. This was accomplished via (i) a promoter library-based combinatorial pathway optimization of the biosynthetic TAN-1612 genes coexpressed with a putative TAN-1612 efflux pump, reducing TAN-1612 toxicity in yeasts while simultaneously increasing supernatant titers and (ii) the development of a medium-throughput UV-visible spectrophotometric assay that facilitates TAN-1612 combinatorial library screening. Through this multipronged approach, we optimized TAN-1612 production, yielding an over 450-fold increase compared to previously reported S. cerevisiae yields. TAN-1612 is an important tetracycline analogue precursor, and we thus present the first step toward generating novel tetracycline analogue therapeutics to combat current and emerging antibiotic resistance. We also report the first heterologous production of a fungal polyketide, like TAN-1612, in the probiotic S. boulardii. This highlights that engineered S. boulardii can biosynthesize complex natural products like tetracyclines, setting the stage to equip probiotic yeasts with synthetic therapeutic functionalities to generate living therapeutics or biocontrol agents for clinical and agricultural applications.
