Abstract
Sweet protein mutants, preparation methods, and use thereof are provided. The sweet protein mutant is obtained by inducing one or more amino acid mutations in a sweet protein with an amino acid sequence shown in SEQ ID NO. 1, the one or more amino acid mutations including at least one of K5D, V7R, D29N, or E53R. By introducing mutations into the amino acid sequence of the sweet protein, the sweetness of the sweet protein mutant is significantly improved compared with the sweet protein corresponding to the original amino acid sequence.
Claims14
A sweet protein mutant, wherein the sweet protein mutant is obtained by inducing one amino acid mutations in a sweet protein with an amino acid sequence shown in SEQ ID NO. 1, the amino acid mutations are K5D+V7R+D29N+E53R.
