Identification of the pMupA I plasmid. The plasmid DNA
digestion patterns for isolate BNM 63 is obtained with
HindIII (lane 1) and Bsu15I (ClaI)
(lane 2) and the results of hybridization of the digested DNA with the
mupA probe (HindIII, lane 5;
Bsu15I [ClaI], lane 6) are shown. Lanes 1 and
4, bacteriophage λ digested by HindIII DNA molecular size
marker (Kucharczyk TE, Warsaw, Poland). DNA bands specific for the
pMupA I plasmid are indicated by arrows.
