    摘要: A yeast promoter comprising the promoter of the (cytoplasmically located glycerol-3-phosphate dehydrogenase gene (GPD 1) possesses advantageous capacity to regulate the expression of heterologous polypeptides in yeasts transformed therewith. Expression of such polypeptides utilizing the GPD1 promoter can be regulated by the presence(repressed) or absence(derepressed) of high levels of sucrose or glucose in the fermentation medium. Alternatively, a non-repressing carbon source, such as glycerol or ethanol, can be added to the fermentation medium.

    摘要: A fusion polypeptide comprising, as at least part of the N-terminal portion thereof, an N-terminal portion of HSA or a variant thereof and, as at least part of the C-terminal portion thereof, another polypeptide except that, when the said N-terminal portion of HSA is the 1-n portion where n is 369 to 419 or a variant thereof then the said polypeptide is one of various specified entities. The HSA-like portion may have additional N-terminal residues, such as secretion leader sequences (signal sequences). The C-terminal portion is preferably the amino terminal fragment of human urokinase-type plasminogen activator. The N-terminal and C-terminal portions may be cleavable to yield the isolated C-terminal portion, with the N-terminal portion having served to facilitate secretion from the host. Such cleavage can be achieved in yeast using a sequence cleavable by the KEX2 protease of S. cerevisiae.
