OriDB is a biological database of confirmed and predicted DNA replication origin sites in the model organisms Saccharomyces cerevisiae and Schizosaccharomyces pombe.

The DNA Replication Origin Database (OriDB) provides access to collated published datasets that have predicted and/or confirmed the location of replication origins. Each potential replication origin site is listed as confirmed, likely or dubious dependent upon the level of supporting data. For each site addition information is available, including:

In addition, there is a graphic viewer that allows users to select chromosomal regions and display selected datasets. All original datasets presented in OriDB are available for download.
