Latest Patents

Neng Xiong's latest patents include a groundbreaking nitrilase mutant designed for the synthesis of an anti-epileptic drug intermediate. This invention features a nitrilase mutant protein with increased thermal stability obtained through specific mutations in amino acids at positions 151, 223, and 250. The mutant AcN-T151V/C223A/C250G demonstrated an impressive thermal stability increase of up to 1.73 folds. Utilizing this mutant, the yield for producing 1-cyanocyclohexyl acetic acid was remarkably high, reaching 95% with a 1M substrate at 35° C, and up to 97% with a 1.2M substrate under the same conditions. Additionally, this mutant was instrumental in synthesizing gabapentin, achieving a final product yield of up to 80%.

Another significant invention by Neng Xiong focuses on a polypeptide tag that enhances the solubility and activity of recombinant nitrilase in pharmaceutical synthesis. By attaching the polypeptide tag to the N-terminus of the nitrilase sequence, Xiong was able to produce a highly soluble and active enzyme. This innovation resulted in a remarkable catalytic activity of 3034.7 U/g dcw, and expedited substrate hydrolysis by 30 minutes compared to the original enzyme.
