Restriction digests of the clone give the following sizes (kb): BamHI--6.6; EcoRI--6.6; SacI/XbaI--3.4, 2.9, 0.48.
The galactokinase (GALS) promoter is a deletion variant of GAL1, which lacks one and a half of the 3 UAS elements required for full induction of the promoter by galactose.
The promoter is tightly repressed by glucose and is induced at a moderate level by galactose.
High copy number shuttle expression vector.
One of 32 yeast expression vectors (ATCC 87318-87349) differing in promoter, selection marker and replicon.
