In the dynamic landscape of pharmaceutical manufacturing, the demand for high-purity chiral intermediates like L-tert-Leucine is ever-increasing. As a leading L-tert-Leucine manufacturer and supplier in China, we are at the forefront of innovation, leveraging advanced enzyme engineering to redefine production standards. This article delves into the cutting-edge biosynthesis of L-tert-Leucine, highlighting the development and advantages of novel fusion enzyme technology.

L-tert-Leucine, recognized for its CAS number 20859-02-3, is a vital chiral building block in the synthesis of critical pharmaceuticals, including anti-tumor and anti-virus drugs. Traditional chemical synthesis methods often face challenges related to environmental impact, energy consumption, and low enantioselectivity. To address these limitations, biocatalysis has emerged as a greener and more efficient alternative.

Our research has focused on developing a sophisticated fusion enzyme, specifically a glucose dehydrogenase-leucine dehydrogenase (GDH–LeuDH) fusion enzyme, denoted as GDH–R3–LeuDH. This innovative approach combines the catalytic power of two essential enzymes into a single, stable protein complex. The fusion enzyme significantly enhances the cofactor regeneration rate, a critical step in the reductive amination process used for L-tert-Leucine synthesis. By effectively recycling the expensive NADH cofactor, the overall catalytic efficiency and economic viability are greatly improved.

The advantages of this fusion enzyme technology are manifold. Firstly, it confers superior structural stability and environmental tolerance, allowing for reactions under a wider range of pH and temperature conditions compared to free enzymes. This robustness is crucial for industrial applications where process optimization is key. Secondly, by bringing the catalytic sites closer together, substrate channeling occurs, leading to a direct transfer of intermediates between the enzymes. This proximity effect minimizes diffusion losses and accelerates the reaction rate.

In practical terms, our advanced biosynthesis process using the GDH–R3–LeuDH fusion enzyme has demonstrated remarkable results. We have achieved an impressive space-time yield of 2136 g/L/day, a figure that significantly surpasses previous benchmarks. This leap in productivity means that companies can now reliably buy L-tert-Leucine in bulk at competitive prices from our China-based facility, ensuring a stable supply chain for their manufacturing needs.
