UPSTREAM ACTIVATION SEQUENCE (UAS) ELEMENTS FROM THE YEAST PHO5 PROMOTER,YEAST HYBRID PROMOTERS ANDVECTORS,HOSTS TRANSFORMED THEREWITHAND PROCES

摘要

Novel upstream activation sites of the yeast PHO5 gene are used to produce inducible yeast hybrid promoters. The yeast hybrid promoters can be used to control transcription of a polypeptide coding region foreign to yeast in a yeast expression vector.
