Restriction digests of the clone give the following sizes (kb): XbaI--7.5; BamHI--7.5; EcoRI--7.5. One of several S. cerevisiae shuttle expression vectors (ATCC 87078-87092) differing in selection marker, reading frame and orientation of the promoter. Vectors YCpIF4, YCpIF5 and YCpIF6 (ATCC 87081-87083) differ only in the reading frame of the multiple cloning site. |
