Molecular structure of the replication origin of a Bacillus subtilis (natto) plasmid, pUH1.


The structure of a 2.0-kb BstEII DNA sequence necessary and sufficient for the replication of a 5.7-kb Natto plasmid, pUH1, which is responsible for gamma-polyglutamate production by Bacillus subtilis (natto), has been characterized by using a trimethoprim resistance gene derived from B. subtilis chromosomal DNA as a selective marker. The 2.0-kb DNA… (More)
