The replication region of a 100-kb desulfurization plasmid (pSOX)
from Rhodococcus sp. strain X309 was localized to a 4-kb KpnI fragment, and its sequence was determined. The amino
acid sequence of one of the predicted open reading frames (ORFs) was related to the putative replication (Rep) protein sequences of the
mycobacterial pLR7 family of plasmids. Three of the five predicted ORF
products were identified by radiolabelling with the Escherichia coli T7 polymerase/promoter system. In E. coli, the
Rep protein of pSOX was apparently synthesized in a shortened form,
21.3 kDa instead of the predicted 41.3 kDa, as a result of an internal initiation. This situation is reminescent of that for some bacterial Rep proteins. A shuttle plasmid was constructed with the pSOX origin,

Characterization of the Basic Replicon of
Rhodococcus Plasmid pSOX and Development of a
Rhodococcus-Escherichia coli Shuttle Vector
, and the chloramphenicol resistance (Cmr) gene from pRF29. This new shuttle plasmid was used to
demonstrate expression of the Bacillus subtilis sacB gene
in a strain of Rhodococcus, rendering it sensitive to the
presence of sucrose.
