The page contains two contents:
General: this table lists the KO entries and their description specific to this pathway, and provides their frequencies in and in the whole dataset.
Profile + homologs: the distribution of the Kegg entries of Ether lipid metabolism Kegg pathway is displayed here. Given a Kegg entry and a genome, a red box indicates that one or more loci have been annotated with, while a green box indicates that no locus/loci has(have) been annotated with it, but it/they is/are part of an Orthologous group in which other members have been annotated with that Kegg entry, so it is likely that this copy(ies) also performs this Kegg function.
