Provides a collection of over 100 000 protein families. FIGfams are sets of isofunctional homologues. Each one contains a set of proteins that are end-to-end homologous and share a common function and can be define as a fourtuple: ID, protein-set, decision-procedure and family-function. Results from the literature are incorporated into the FIGfams via Subsystem curation, guaranteeing that the FIGfams remain up to date.
