Abstract
The nucleotide sequence of cryptic plasmid (designated as pBL90) detected in the cells of Brevibacterium lactofermentum DSM 1412 was determined. The length of plasmid DNA is 67826 bp. Comparison of the nucleotide sequence of pBL90 with known plasmid sequences showed no long regions of significant homology. Computer analysis of the plasmid DNA revealed 29 open reading frames (ORFs). The amino acid sequences of 15 ORFs (approximately 25% of plasmid length) have a high (>70%) level of identity to proteins from different plasmids of Corynebacterium representatives, including replicative proteins. Unusual in pBL90 is the presence of replicative genes from two different families and types of replication.
