Restriction digests of the clone give the following sizes (kb): BglII--4.1; EcoRI--4.1; BglII/EcoRI--3.2, 0.9. The marker and promoter are flanked by the F4 primer site(5') and the R6 primer site (3'). The size of the the F4/R6 PCR product should be 1482nt. F4 primer sequence: 5'-(gene-specific sequence)GAATTCGAGCTCGTTTAAAC-3'. R6 primer sequence: 5'-(gene-specific sequence) CATTGTATATGAGATAGTTGA-3'. Contains a functional truncated (700 nt) ADH promoter. The promoter is not down regulated during the exponential phase. |
