The invention provides an aspartase mutant and a method for producing R-3-aminobutyric acid by using the aspartase mutant, and belongs to the field of enzyme engineering. The amino acid sequence of the mutant is obtained by carrying out one or more mutations on the sequence shown in SEQ ID NO.3. The invention relates to a mutation site sequence of the gene, which comprises one or more mutation sites in four mutation sites of 237th site (T237C), 31V site (I31V), 88N site (K88N) and 123 site (G123S). The aspartase mutant disclosed by the invention has the advantages of high catalytic property and high selectivity, and a thallus obtained by fermentation can catalyze a 300g/L substrate, which is the highest substrate concentration reported at present. When the catalyst is used for synthesizing the R-3-aminobutyric acid, the generation rate and chiral purity of the R-3-aminobutyric acid can reach 99% or above within 7 hours. Compared with a previous chemical synthesis method and a biological ...
