Hierarchical catalog of orthologs with focus on comparative analyses of genome sequences
OrthoDB is a comprehensive catalog of orthologs, i.e. genes inherited by extant species from their last common ancestor. Arising from a single ancestral gene, orthologs form the cornerstone for comparative studies and allow for the generation of hypotheses about the inheritance of gene functions. Each phylogenetic clade or subclade of species has a distinct common ancestor, making the concept of orthology inherently hierarchical. From its conception, OrthoDB explicitly addressed this hierarchy by delineating orthologs at each major species radiation of the species phylogeny. The more closely related the species, the more finely-resolved the gene orthologies.

STRING provides functional protein association networks from information about interactions (physical and functional) between proteins.
Data from various sources are aggregated using an easy to use web-based interface. After entering a protein name/sequence, a network of different types of interactions (color-coded) is displayed: experimentally verified, based on the genetic context (neighborhood, fusions, co-occurrence), derived from textmining, due to co-expression or based on protein homology.
The network can be recentered on other proteisn, and further information can be displayed for each individual protein (gene names, protein domains, 3D structures, etc.). Links to further databases are provided (e.g. NCBI, KEGG, UniProt, PDB). There are different viewing functionalities across species like neighborhood (adjacent genes of similar proteins) or fusion (identify fusion proteins). The data can be exported in various formats and an API for developers is available. It is even possible to download the raw data that is used by STRING to generate the network; they are provided under a Creative Commons license.
