Lactobacillus bulgaricus proteinase expressed in Lactococcus lactis is a powerful carrier for cell wall-associated and secreted bovine beta-lactoglobulin fusion proteins

Research has been conducted on Lactobacillus bulgaricus extracellular proteinase. The efficient expression of the full-length or truncated forms of this proteinase with different secretion patterns carried out via the use of the expression vector constructs is reported.
