E. coli-derived upstream regulatory sequence operable in yeast

摘要

A hybrid upstream regulatory sequence including an upstream regulatory sequence of E.coli origin and yeast upstream regulatory sequence, which hybrid upstream regulatory sequence can function in a yeast cell; a hybrid promoter including the regulatory sequence of E.coli origin and a TATA region of a yeast promoter, which hybrid promoter can also function in a yeast cell; a hybrid promoter including the upstream regulatory sequence of E.coli origin and a yeast promoter, which hybrid promoter can function in a yeast cell; and a plasmid useful for a test of an upstream regulatory sequence, including a TATA region of a yeast promoter, a structural gene containing a translation start codon, and a yeast origin of replication.
