Abstract: The present disclosure belongs to the technical field of genetic modification of an enzyme preparation and particularly relates to a preparation method of a high-stability superoxide dismutase with a transmembrane capability. The method includes the following steps: extracting mRNA from Geobacillus stearothermophilus, synthesizing cDNA by a reverse transcription method, amplifying a large number of coding regions of the cDNA by designing a specific primer, ligating the coding regions to an E. coli expression vector, and transforming the coding regions into engineering bacteria BL21 (DE3). A point mutation technology is used to enhance stability of the superoxide dismutase and a flexible polypeptide linker GGGSGGGS (SEQ ID NO: 11) is designed, such that a soluble fusion expression of a transmembrane peptide YGRKKRRQRRR (SEQ ID NO: 10) and the superoxide dismutase is successfully realized.
