Database Description
OriDB provides a web-based catalogue of confirmed and predicted DNA replication origin sites. At present this is limited to budding yeast (S. cerevisiae). Each proposed or confirmed origin site appears as a record in OriDB, with each record comprising seven pages. These pages provide, in text and graphical formats, the following information: genomic location and chromosome context of the origin site; time of origin replication; DNA sequence of proposed or experimentally confirmed origin elements; free energy required to open the DNA duplex (stress-induced DNA duplex destabilization or SIDD); and phylogenetic conservation of sequence elements. In addition, OriDB encourages community submission of additional information for each origin site through a User Notes facility. Origin sites are linked to several external resources, including the Saccharomyces Genome Database (SGD) and relevant publications at PubMed. Finally, a Chromosome Viewer utility allows users to interactively generate graphical representations of DNA replication data genome-wide. OriDB is accessible at http://www.oridb.org/.
Recent Developments
Upcoming extensions of OriDB will include the incorporation of additional budding yeast datasets and a parallel databases for fission yeast (S. pombe) replication origins (as datasets are described).
