title: A 50-kb plasmid rich in mobile gene sequences isolated from a marine micrococcus.
abstract: A 50,709-bp cryptic plasmid isolated from a marine Micrococcus has been sequenced and found to contain a number of putative mobile genetic elements. The coding regions for 11 putative transposases comprise approximately 17% of the total plasmid sequence. The majority of these transposases are located within a 13-kb cluster which includes a 1553-bp direct repeat consisting of a duplicated pair of transposase genes. The remaining putative ORFs showed similarity to a variety of proteins, the most notable being spider silk.
