Résumé

L-phosphinothricin (L-PPT) is the most popular broad-spectrum and highly effective herbicide. Transaminases (TAs) play a pivotal role in asymmetric synthesis of L-PPT, yet encounter the challenge of unfavorable reaction equilibrium. In this study, the novel dual transaminases cascade system (DTCS) was introduced to facilitate the synthesis of L-PPT. The specific amine transaminase BdATA, originating from Bradyrhizobium diazoefficiens ZJY088, was screened and identified. It exhibited remarkable activity, good stability, and required only 2.5 equivalents of isopropylamine to transform pyruvate effectively. By coupling BdATA with previously reported SeTA to construct the DTCS for pyruvate removal in situ, the L-PPT yield escalated from 37.37 % to 85.35 %. Three advantages of the DTCS were presented: the removal of pyruvate alleviated by-product inhibition, the use of isopropylamine reduced reliance on excess L-alanine, and no demand for expensive cofactors like NAD(P)H. It demonstrated an innovative idea for addressing the challenges associated with transaminase-mediated synthesis of L-PPT.
