Restriction digests of the clone give the following sizes (kb): BglII--4.4; EcoRI--2.9, 1.5; PstI--4.4; BamHI--3.2, 1.2; XbaI--4.4. Contains a HIS4C/URA3 fusion cassette that can be used to make fusions to other proteins of interest. Also includes a M13 sequencing primer approximately 300 bp from the HIS4C/URA3 fusion junction. Encodes 93 amino acids of HIS4C and the complete 267 amino acids of URA3. Can be used for promoter/enhancer trap screens. Constructed from pNKY48 (ATCC 77182) by inserting an EcoRI 8-mer at the HindIII site in the polylinker. The order of the major features in this plasmid is: M13 primer - ClaI - XhoI - SalI - XbaI (stop) - BamHI - EcoRI - HIS4C bridge/URA3 - BamHI - HindIII - BglII - NcoI - EcoRI - M13 ori - pMB1 ori - ampR. |
