Abstract
The citrate plasmid (Cit+ plasmid) from Lactococcus lactis subsp. lactis biovar diacetylactis was cloned into the EcoRI site of plasmid pUC18. This recombinant plasmid enabled Escherichia coli K-12 to transport and utilize citrate as a source of energy, indicating expression of the citrate permease from L. lactis biovar diacetylactis. The citrate permease was under the control of the lac promoter of pUC18. Genetic expression of the Cit+ plasmid in maxicells revealed that the plasmid encoded two polypeptides of 47 and 32 kilodaltons, determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.Entities:
