Enhanced Recombinant Protein Production of Soluble, Highly Active and Immobilizable PNGase F.


ABSTRACT: High resolution analysis of N-glycans can be performed after their endoglycosidase mediated removal from proteins. N-glycosidase F peptide (PNGase F) is one the most frequently used enzyme for this purpose. Because of the significant demand for PNGase F both in basic and applied research, rapid and inexpensive methods are of great demand for its large-scale production, preferably in immobilizable form to solid supports or surfaces. In this paper, we report on the high-yield production of N-terminal 6His-PNGase F enzyme in a bacterial Escherichia coli SHuffle expression system. The activity profile of the generated enzyme was compared to commercially available PNGase F enzymes, featuring higher activity for the former. The method described here is thus suitable for the cost-effective production of PNGase F in an active, immobilizable form.
