Isolation, sequence analysis, and comparison of two plasmids (28 and 29 kilobases) from the biomining bacterium Leptospirillum ferrooxidans ATCC 49879

Two plasmids of 28,878 bp and 28,012 bp are isolated from Leptospirillum ferrooxidans ATCC 49879. A total of 67 open reading frames (ORFs) are identified on both plasmids, of which 32 has predicted products with high homology to proteins of known function while 11 ORFs has predicted products with homology to previously identified proteins of unknown function.
