A plasmid able to transform and to be stably maintained both in
Sulfolobus solfataricus and in Escherichia coli
was constructed by insertion into an E. coli plasmid of the
autonomously replicating sequence of the virus particle SSV1 and a
suitable mutant of the hph (hygromycin phosphotransferase)
gene as the transformation marker. The vector suffered no rearrangement
and/or chromosome integration, and its copy number in
Sulfolobus was increased by exposure of the cells to
mitomycin C.
