BACKGROUND Currently, the two most commonly used fibrinolytic agents in thrombolytic therapy are recombinant tissue plasminogen activator (rt-PA) and streptokinase (SK). Whereas SK has the advantage of substantially lower costs when compared to other agents, it is less effective than either rt-PA or related variants, has significant allergenic potential, lacks fibrin selectivity and causes tran...

Bovine follicle-stimulating hormone (bFSH), a pituitary gonadotropin, is a heterodimer hormone that consists of a common alpha-subunit non-covalently associated with the hormone-specific beta-subunit. Unfortunately, expression levels of recombinant bFSH or its subunits are invariably low. We report here the secretory expression of biologically active bFSHalpha and bFSHbeta subunit in the methyl...

Presently almost no information is available on the oligosaccharide structure of the glycoproteins secreted from the methylotrophic yeast Hansenula polymorpha, a promising host for the production of recombinant proteins. In this study, we analyze the size distribution and structure of N-linked oligosaccharides attached to the recombinant glycoprotein glucose oxidase (GOD) and the cell wall mann...

In yeast and filamentous fungi, sulfide can be condensed either with O-acetylhomoserine to generate homocysteine, the precursor of methionine, or with O-acetylserine to directly generate cysteine. The resulting homocysteine and cysteine can be interconverted through transsulfuration pathway. Here, we systematically analyzed the sulfur metabolic pathway of the thermotolerant methylotrophic yeast...

During the last decade methylotrophic yeasts have gained increasing interest, both for fundamental (van der Klei and Veenhuis, 1996) and applied purposes (van Dijk et al., 2000; Gellissen, 2000). The special value of these yeasts (mainly Pichia pastoris and Hansenula polymorpha) in fundamental research is undoubtedly related to studies on the principles of peroxisome homeostasis (biogenesis vs....

Aromatic amino acid auxotrophs of the methanol-utilizing yeast Hansenula polymorpha were effectively selected by the use of nystatin and a medium that inhibits the growth of tyrosine auxotrophs. The procedure resulted in a frequency of aromatic auxotrophs of 2% of survivors and an enrichment of 20-fold. The new procedure also takes less time than traditional procedures. Of the auxotrophic mutan...
