DNA fragment containing gene which encodes the function of stabilizing plasmid in host microorganism.

摘要

A DNA fragment derived from plasmid pBY503 harboring Brevibacterium stationis IFO12144, said DNA fragment containing a gene which encodes for the function of maintaining a plasmid, capable of replicating and proliferating at least in a Coryne-form bacteria of the genus Brevibacterium, stably in said bacteria; and a vector DNA capable of replicating and proliferating in a Coryne-form bacteria into which the above DNA fragment is introduced.
