Latest Patents
One of his latest patents is titled "Method for enzymatic preparation of R-3 aminobutyric acid." This method boasts high efficiency and high stereoselectivity. It utilizes aspartase with stereoisomerization catalytic activity to convert butenoic acid into R-3-aminobutyric acid. Remarkably, after just 24 hours of reaction, the conversion rate reaches ≥98%, with an enantiomeric excess (ee) value of ≥99.9%. This method not only improves conversion efficiency but also shortens reaction time and reduces production costs. It features a high yield, low costs, a short production cycle, and a simple process, making it suitable for mass production.
Another notable patent is "Highly active S-cyanohydrin lyase and application thereof." This invention provides a highly active S-cyanohydrin lyase obtained by mutating an amino acid residue at position 103 of a wild-type cassava S-cyanohydrin lyase. The mutation significantly increases the expression of the mutant enzyme without requiring a decrease in temperature during induction. Further mutations at position 128 and other sites have resulted in mutants with enhanced catalytic activity.
