Title Molecular dissection of a bifidobacterial replicon.
Journal Appl. Environ. Microbiol.
Abstract The 2.1-kb cryptic plasmid pCIBAO89 from Bifidobacterium asteroides harbors a 1.4-kb segment which is sufficient for its autonomous replication. The segment is divided into two parts, the presumed replication origin, ori89, and the rep gene encoding the putative 41-kDa Rep89 replication initiation protein. This minimal replication region of pCIBAO89 was functionally dissected by transcriptional analyses as well as by DNA-binding studies, and the information obtained was exploited to create a number of Escherichia coli-Bifidobacterium shuttle vectors capable of transforming various bifidobacteria with an efficiency of up to 10(6) transformants/mug DNA.
