Bifidobacteria possess a unique genomic capability for N-glycan cleavage. Recombinantly producing these enzymes would be a promising novel tool to release bioactive N-glycans from glycoprotein-rich substrates such as colostrum.

Bovine colostrum is both a primary source of nutrients and immunological support for the newborn calf. The understanding of the level of therapeutic proteins (lactoferrin and IgG) is important for the bovine colostrum dosing and standardization for human consumption.
