Production of Vespa tropica Hyaluronidase by Pichia pastoris.

ABSTRACT: Hyaluronidases have been a subject of great interest in medical and cosmeceutical applications. Previously, our group demonstrated that the venom glands of Vespa tropica contain hyaluronidase enzymes (VesT2s), and heterologous expression of the corresponding gene (VesT2a) in E. coli systems results in inclusion bodies, necessitating functional folding using urea. Here, we report the successful heterologous expression of VesT2a in the Pichia pastoris expression system, with gene construction achieved using GoldenPiCS. After confirming gene integration in the yeast genome, methanol-induced cultures yielded an exceptional amount of VesT2a, approximately two-fold higher than that obtained with the constitutive expression vector (P_GAP).
