Heterologous expressing melittin in a probiotic yeast to evaluate its function for promoting NSC-34 regeneration.

ABSTRACT: Melittin is a bioactive peptide and the predominant component in bee venom (BV), studied for its many medical properties, such as antibacterial, anti-inflammatory, anti-arthritis, nerve damage reduction, and muscle cell regeneration. Melittin is primarily obtained through natural extraction and chemical synthesis; however, both methods have limitations and cannot be used for mass production. This study established a heterologous melittin expression system in the probiotic yeast Kluyveromyces marxianus. This yeast was selected for its advantages in stress tolerance and high secreted protein yields, simplifying purification. A > 95% high-purity melittin (MET) and its precursor promelittin (ProMET) were successfully produced and purified at 1.68 μg/mL and 3.33 μg/mL concentrations and verifie
