Abstract
Leuconostoc citreum CBUE isolated from kimchi proved to harbor a small cryptic plasmid, pNS75. The complete nucleotide sequence of pNS75 was 1,821 bp and had a low G+C content of 39.2%. Computer analysis using DNASIS revealed one open reading frame (ORF), having ATG as putatitive start condon and potentially encoding proteins with molecular mass of 38 kDa. The chimeric plasmid pLeuCM was first constructed wih pNS75, pUC19 and chroamphenicol acetyltransferase (CAT) from Staphylococcus sp.. pLeuCM replicated and expressed chroamphenicol acetyltransferase in Leuconostoc citerum CBNF after transformation. To test the availability of shuttle vector as cloning vehicle of foreign gene,
