Restriction digests of the clone give the following sizes (kb): EcoRI--2.4, 1.1, 1.0; KpnI/SmaI--4.6; PvuII/PstI--2.5, 2.0; KpnI--4.6; SmaI--uncut. Contains the basic replicon of pPS10 which has been sequenced (EMBL accession number X58896). The repA portion is flanked by EcoRI sites (nt 536 and 1500), with the site at nt 536 between the repA promoter and coding sequences. General purpose vector. Constructed by excising a BamHI/HindIII fragment encoding part of kanR from pCN40 (ATCC 77097), blunting with Klenow fragment, and religating. |
