✦ Synopsis

The nucleotide sequence of the cis-acting partition site (centromere) of the miniF plasmid has been determined. Its most notable feature is a reiterated 43 base pair unit. A series of plasmids deleted for portions of the repeat region was constructed and tested for incompatibility with R386 and for stability of inheritance. The extent of incompatibility with R386 was correlated with the number of repeat units. In contrast, the great majority of the repeats were not needed for miniF stability. An adjacent region of unique sequence was also found to be involved in centromere function.
