OriDB provides a catalogue of confirmed and predicted DNA replication origin sites. At present this is limited to budding yeast (S. cerevisiae) and fission yeast (S. pombe). If you use OriDB, please cite our paper.

This website provides access to and searching of the database. The data have been collated by Conrad Nieduszynski as the culmination of a number of genome-wide studies to identify the location of replication origins throughout the budding yeast genome. In addition to the genome-wide studies data from a large number of other origin mapping and characterization studies have been included.
