Abstract: Replication origins have been mapped to positions that coincide, within experimental error (several hundred base pairs), with ARS elements. To determine whether the DNA sequences required for ARS function on plasmids are required for chromosomal origin function, the chromosomal copy of ARS306 was deleted and the chromosomal copy of ARS307 was replaced with mutant derivatives of ARS307 containing single point mutations in domain A within the ARS core consensus sequence. The chromosomal origin function of these derivatives was assayed by two-dimensional agarose gel electrophoresis. Deletion of ARS306 deleted the associated replication origin. The effects on chromosomal origin function of mutations in domain A paralleled their effects on ARS function, as measured by plasmid stability. These results demonstrate that chromosomal origin function is a property of the ARS element itself.
