    Abstract: PURPOSE: Human serum albumin is over expressed in Hansenula polymorpha DL-1 transformed with HSA gene under the control of methanol oxidase gene promoter. CONSTITUTION: The invention is disclosed transformed yeasts Hansenula polymorpha DL-1 which has integrated HSA gene, isolated from human fetal liver cDNA library and removed 5'UTR without signal sequence, controlled by methanol oxidase gene promoter. Transformed yeast is cultured in YPM medium( 1 % of yeast extract, 2 % of Bacto peptone, and 2 % of methanol) at 37°C for 72 hrs. Methanol is supplied at every 12 hrs to keep the concentration 2 % of methanol in the medium constant after 24 hrs. The concentration of expressed HSA is 40-50 mg/l by western blotting compared with authentic standard HSA. This method also detects smaller degraded HSA proteins in the medium.

    Abstract: The hirudin expression vector pYEGa-HIR5 (KCTC 8518P) containing hirudin gene (I) consists of linked promoter GAL1-GAL10, alpha factor of yeasts (a on plasmid means alpha), peptide sequence for leu-asp-lys-arg which is hydrolyzed by KEX2 as operator endopeptidase and hirudin gene. The other plasmid pYEGa-HIR525 (KCTC 8519BP) (II) consists of GAL10 as promoter rather than GAL1-GAL10 of (I). (I) and (II) are useful for yeast expression to solve the problems which in E. coli the expressed hirudin is hydrolysed and the N-terminal methionine modified hirudin does not have the activity.
