Restriction digests of the clone give the following sizes (kb): BglI--2.7, 1.6; PvuI--2.6, 1.7; EcoRI--4.3. One of 9 shuttle vectors (ATCC 87585 - 87593) allowing lacZ detection of cloned inserts and containing the pUC19 MCS with all 10 cloning sites unique. Vectors differ in mode of replication (YE, YC or YI-type) and yeast marker (LEU2, URA3 or TRP1). The EcoRI and KpnI restriction sites from the LEU2 gene of S. cerevisiae were removed by using oligo-directed mutagenesis. |
