Abstract[English]
Provided are engineered transaminase polypeptides for the synthesis of Ubrogepant intermediates with high stereoselectivity, high catalytic activity and good stability. Also provided is a reaction process for the asymmetric synthesis of Ubrogepant intermediates using the transaminase polypeptide.[French]
La présente invention concerne des polypeptides transaminases modifiés pour la synthèse d'intermédiaires d'Ubrogepant présentant une stéréosélectivité élevée, une activité catalytique élevée et une bonne stabilité. La présente invention concerne également un procédé de réaction pour la synthèse asymétrique d'intermédiaires d'Ubrogepant à l'aide du polypeptide transaminase.
