  • ENGINEERING STRAIN PRODUCING CORDYCEPIN AND ITS DERIVATIVE 3'-DEOXYINOSINE, ITS PREPARATION METHOD AND APPLICATION
    Publication number: 20240344099
    Abstract: The present invention relates to the field of genetic engineering and process engineering, and discloses an engineering strain producing cordycepin and its derivative 3?-deoxyinosine, its preparation method and application. The method includes: codon optimizing genes Cm1 and Cm2; gene amplification and fragment recovering; methanol-induced promoter and terminator fragments; and inserting the genes into an expression vector and then transferring to Pichia pastoris for screening to obtain the engineering strain of Pichia pastoris of the present invention. The engineering strain can be applied to production of cordycepin and its derivative. The engineering strain prepared by the preparation method of the present invention has great advantages in producing cordycepin and its derivative.
