KOALA (KEGG Orthology And Links Annotation) was originally developed as KEGG's internal annotation tool for KO (K number) assignment using SSEARCH computation. Three variants of this tool are available for assigning K numbers to the user's sequence data: BlastKOALA and GhostKOALA using BLAST and GHOSTX searches, respectively, and KofamKOALA served by GenomeNet using the HMM profile search. The new version of BlastKOALA introduced on April 1, 2023 searches a small subset of KEGG GENES containing KEGG reference genomes and individual sequences linked from pubmed records of KO entries, rather than a much larger nonredundant dataset [1].    See Step-by-step Instructions.



Upload query amino acid sequences in FASTA format
Enter FASTA sequences

Or upload file:
Your query data consisting of multiple amino acid sequences will be given K numbers by BlastKOALA.
Up to 50,000 sequences may be uploaded.

Enter KEGG GENES database file to be searched
Eukaryotes
Prokaryotes
Viruses
Prokaryotes and eukaryotes contain sequences of KEGG reference genomes and sequences linked from pubmed records of KO data. The size of each dataset is about 600-700 thousand sequences.
