  • 17?-hydroxysteroid dehydrogenase mutants and application thereof
    Patent number: 11098287
    Abstract: The disclosure discloses 17?-hydroxysteroid dehydrogenase mutants and application thereof, and belongs to the technical field of biology. The disclosure provides 17?-hydroxysteroid dehydrogenase mutants V107A, T155N, H164Y and V107A/T155N/H164Y with high specific enzyme activities, and the specific enzyme activities of the 17?-hydroxysteroid dehydrogenase mutants V107A, T155N, H164Y and V107A/T155N/H164Y are as high as 1.85, 1.93, 2.06 and 5.15 U/mg, respectively, which are 1.11, 1.16, 1.24 and 3.10 times larger than that of wild-type 17?-hydroxysteroid dehydrogenase (1.66 U/mg).
    Type: Grant
