To facilitate the development of mycoplasmal cloning vectors, we have determined the nucleotide sequence of pKMK1, a cryptic plasmid isolated from Mycoplasma mycoides subsp. mycoides. It is 1875 bp in length and contains two open reading frames (ORFs) that share homology with ORFs from members of a large family of gram-positive bacterial plasmids which replicate via a single-stranded DNA intermediate. Putative origins of replication and candidate cloning sites have been identified. © 1992.
