Every translated protein across the federated catalog, derived from a genome record each node already holds (translated from its coding sequence, not newly ingested). Individual proteins are also reachable from their parent genome (/species/[id] lists each genome's proteins) — this page is the browsable index of all of them.
Cross-Spoke ortholog clustering, grouping proteins across the federated catalog by pairwise sequence similarity — a real analysis-platform capability, computed on demand since it runs over the entire protein catalog.
