A new mutant of D-amino acid transaminase, based on supercomputing-assisted technology, belongs to the fields of computational biology, computer-aided design, and enzyme engineering technology, and specifically relates to mutants of D-amino acid transaminase obtained based on supercomputing-assisted technology and applications thereof. Compared to the wild-type enzyme, the aforementioned mutant of D-amino acid transaminase exhibits a half-life (t1/2) of over 12 hours at 40° C., while it is only 8.8 minutes for the wild-type D-amino acid transaminase. The half-inactivation temperature (T505) of the mutant is 45.3° C., approximately 5.4° C. higher than that of the wild-type D-amino acid transaminase. This substantially enhances its thermal stability, enzymatic activity, etc., effectively broadening its application fields and scope.
