GhostKOALA assigns K numbers to the user's sequence data by GHOSTX search against a nonredundant set of KEGG GENES [1]. This service will be re-evaluated due to the increasing size of the dataset, which is an order of magnitude larger than that for the new version of BlastKOALA.    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 GhostKOALA.
The file size of up to 300 MB with the limit of 500,000 sequences may be uploaded.

Enter KEGG GENES database file to be searched
genus_prokaryotes + virusess
genus_prokaryotes + family_eukaryotes + viruses
Each of the nonredundant datasets, genus_prokaryotes and family_eukaryotes, contains about 10 million sequences.
