    Area of Science:

    • Biotechnology
    • Molecular Biology
    • Synthetic Biology

    Background:

    • Oxyntomodulin is a peptide hormone with potential therapeutic applications.
    • Efficient and scalable production of recombinant proteins is crucial for biotechnology.
    • Intein-mediated protein ligation offers a novel approach for protein engineering.

    Purpose of the Study:

    • To develop a method for producing synthetic oxyntomodulin using recombinant DNA technology.
    • To construct and express a hybrid gene encoding oxyntomodulin and an intein in Escherichia coli.
    • To investigate the properties and autocatalytic cleavage of the expressed hybrid protein.

    Main Methods:

    • Chemical and enzymatic synthesis of an artificial oxyntomodulin gene.
    • Construction of a recombinant plasmid with the hybrid gene and Ssp dnaB intein.
