▽no title ●09/01 03:54 All genome pairs in KEGG are subject to SSDB (Sequence Similarity DataBase) computation using the SSEARCH program for both amino acid sequences (protein coding genes) and nucleotide sequences (RNA genes). For each gene, an organism-based list of similarity neighbors is generated and displayed in a tabular form, called GFIT table. It shows the best hit sequence in each matching organism, as can be
