Restriction digests of the clone give the following sizes (kb): KpnI--5.0, 1.8; SstI--6.7; HindIII--6.7. Shuttle vector transforming S. pombe at high efficiency. Suitable for generating nested deletions, DNA sequencing, and producing riboprobes. Permits visual detection of recombinants by lacZalpha complementation. Constructed from pRS305 by inserting a 1.2 kb EcoRI fragment containing ars1 into the AatII site. The NdeI site in ars1 was removed. The order of the major features (with directions of transcription) is: < LEU2 - f1 - < lacZ' - SacI/MCS/KpnI - pMB1 ori - < ampR - ars1. |
