The IncI alpha plasmid R64 was found to bear a highly mobile DNA segment which was designated as a clustered inversion region (J. Bacteriol. 165, 94-100, 1986). The clustered inversion region consists of four DNA segments designated respectively as A, B, C and D which differ in molecular size and restriction sites. The four DNA segments invert independently(More)
The developmentally regulated gene dofA, identified from pulse-labeling experiments by two-dimensional gel electrophoresis, and its homologue, dofB, were cloned and characterized in Myxococcus xanthus. Deletion of dofA and dofB did not affect the vegetative growth and development of M. xanthus. dofA was specifically expressed during development, while dofB(More)
The shufflon, a multiple DNA inversion system in the plasmid R64, consists of four DNA segments flanked and separated by seven 19-bp repeat sequences. Site-specific recombinations mediated by the rci product occur between each inverted repeat sequence, resulting in inversions of the four segments independently or in groups. The seven 19-bp repeat sequences(More)
The initiation of replication from oriV RSF1010, the replication origin of the broad host-range plasmid RSF1010, depends on RepA (helicase), RepB' (primase), and RepC (initiator protein), encoded by RSF1010 itself, while this initiation event in E. coli is independent of dnaA, dnaB, dnaC, and dnaG [Scherzinger et al. (1984) Proc. Natl. Acad. Sci. USA 81,(More)
