Uniprot vs uniprotKB

Question

[david.zlotkin]

I saw that foldseek enables downloading the alphafold uniprot DB, and also uniprot50. Is it the same DB as the uniref50 that is downloadable in mmseqs2?

Thanks!

UniProt creates UniRef50 using mmseqs2. If foldseek uses uniref50.fasta from UniProt then it should be the same database.
