Nucleotide sequence and analysis of pBL1, a bacteriocin-producing plasmid from Lactococcus lactis IPLA 972.

abstract：:Nucleotide sequence analysis of the Tn4451-deletion derivatives, pJIR47 and pJIR86, which were derived from Escherichia coli and Clostridium perfringens, respectively, showed that the deletion events that led to the formation of these plasmids were identical and precise. The results also showed that the termini of thi...
