Background: The Need for Rational Biocatalytic Reaction Route Development

Biocatalysis has become a central technology for sustainable chemical manufacturing, offering high selectivity, mild reaction conditions, and reduced environmental impact compared with traditional chemical synthesis. However, the successful industrial deployment of biocatalytic processes depends not only on individual enzyme performance but also on the coordinated design and optimization of entire reaction routes within living systems or enzymatic cascades.

Biocatalytic reaction routes are inherently complex. They involve multiple enzymatic steps, interconnected metabolic pathways, global cellular regulation, cofactor balancing, and competition with native metabolic functions. Traditional trial-and-error approaches are often insufficient to navigate this complexity efficiently, particularly when aiming for high yield, productivity, robustness, and scalability.

Biocatalytic reaction route development addresses this challenge by integrating multiple layers of biological and engineering optimization. Rather than treating pathway design, strain engineering, and process development as isolated tasks, this service adopts a holistic, systems-level perspective. By combining rational design with data-driven optimization and combinatorial exploration, biocatalytic reaction routes can be engineered to meet both technical and commercial objectives.

What We Offer: A Modular and Integrated Service Portfolio

We provide a flexible yet comprehensive portfolio of services that can be deployed individually or as an integrated development program, depending on project maturity and customer needs.

Services		Price
Metabolic Flux Analysis for Biocatalytic Systems	Metabolic flux analysis (MFA) provides quantitative insight into intracellular metabolic states by determining the distribution and magnitude of metabolic fluxes. Using stoichiometric, isotope-assisted, and hybrid modeling approaches, MFA enables the identification of pathway bottlenecks, competing reactions, and cofactor imbalances. These insights guide rational engineering decisions and reduce experimental uncertainty during route optimization.	Inquiry
Synthetic Pathway Design for Biocatalysis	Synthetic pathway design focuses on the identification, assembly, and optimization of biosynthetic routes capable of producing target compounds efficiently. By leveraging databases, bioinformatics tools, and enzyme engineering knowledge, synthetic pathways are designed to maximize theoretical yield, thermodynamic feasibility, and host compatibility. Both native and heterologous pathways are evaluated and engineered to meet application-specific goals.
Genome Engineering for Biocatalytic Pathway Optimization	Genome engineering introduces multiplex, genome-wide perturbations to globally reshape cellular behavior in favor of product formation. Using technologies such as CRISPR-based multiplex editing, MAGE, and randomized genome-wide approaches, large strain libraries are generated and screened to discover superior phenotypes. Genome engineering is particularly powerful for improving tolerance, robustness, and pathway expression balance.
Integrated Metabolic Pathway Engineering for Biocatalysis	Integrated metabolic pathway engineering combines pathway design, modular optimization, flux analysis, and large-scale gene editing to systematically enhance biosynthetic performance. Strategies such as multi-modular optimization, enzyme scaffolding, metabolic flux redistribution, and pathway library construction are applied to achieve high-yield, scalable production strains.

Case Studies: Biocatalytic Reaction Route Development in Practice

Case 1: Modular Whole-Cell Cascades for Green DCA Production

Aliphatic α,ω-dicarboxylic acids (DCAs) are important industrial chemicals traditionally produced through energy-intensive and environmentally harmful chemical oxidations. This study presents an environmentally friendly in vivo biocatalytic cascade for converting cycloalkanes into DCAs. To alleviate protein expression burden and redox imbalance, the synthetic pathway was distributed across three engineered E. coli cell modules, each designed with either redox-neutral or redox-regenerating functions. These modules were assembled into microbial consortia that efficiently catalyze multistep oxidations without external cofactors. The modular whole-cell system achieved effective conversion of cycloalkanes and cycloalkanols to DCAs, demonstrating a scalable and sustainable alternative to conventional DCA manufacturing processes.

Case 2: Integrated Bio- and Chemocatalytic Routes to Niraparib

This work describes the development of two improved asymmetric synthetic routes to the PARP inhibitor niraparib, integrating biocatalysis and chemocatalysis for efficient API production. Enantioselective synthesis of a key 3-aryl-piperidine fragment was achieved via novel transaminase-mediated dynamic kinetic resolution of stable aldehyde surrogates, expanding the scope of biocatalytic amination. Late-stage convergence relied on a high-yielding, regioselective copper-catalyzed N-arylation with an indazole derivative. Extensive microscale high-throughput experimentation accelerated optimization. Compared with earlier routes, the new processes deliver significantly higher overall yields, reduced step count, improved scalability, and lower cost and environmental impact, demonstrating the power of combined bio- and chemocatalytic process design.
