RESUMO
A small cryptic plasmid, pMBB1, isolated from Enterococcus faecium 226 was characterized. The plasmid contained an extremely stable replicon which has limited homology to the lactococcal plasmid pCI305. Sequence analysis of the replicon detected one open reading frame of 822 bp capable of encoding a 32-kDa protein. No detectable single-stranded intermediates were found for the replicon, suggesting that pMBB1 may be included in the same family as pCI305, although pCI305 exhibits a more narrow host range. A small stably maintained vector able to replicate in a variety of lactic acid bacteria, containing a large multiple cloning region, was constructed by using the pMBB1 replicon.
