2 different kinds of transgenic mice containing human lysozyme genomic DNA-based constructs with different signal peptide DNA are respectively established as system models
a large polymannose (Man310GlcNAc2) chain-linked lysozyme is predominantly expressed in Saccharomyces cerevisiae accompanied by small amounts of a core-type oligomannose chain (Man14GlcNAc2)-linked lysozyme in the yeast medium where the extracellular pH is kept at 3.5 or above, while an oligomannose chain lysozyme is preferentially expressed in the yeast medium where the pH is less than 3

T4 lysozyme is cloned into the yeast expression vector pPIC9K under the control of the Pichia pastoris glyceraldehyde-3-phosphate dehydrogenase promoter and expressed at high level in Hansenula polymorpha strain A16, the enzyme is secreted
two serine-rich heptapeptides, Ser-Ser-Ser-Lys-Ser-Ser-Ser (S6K) and Ser-Ser-Ser-Ser-Ser-Ser-Ser (S7) are fused to the C-terminus of chicken lysozyme by genetic modification. The cDNAs of S6K-lysozyme and S7-lysozyme are inserted into the expression vector of Pichia pastoris and secreted in the yeast cultivation medium. The secretion amounts of S6K-lysozyme and S7-lysozyme are about 60% of that of wild-type lysozyme
