Table 4 Counts of predicted rumen metagenomic proteins and their KO group. Summary of 2774 predicted proteins from the 8 metagenomic rumen samples. KEGG ID is the predicted K0 group. Columns show the number of full length candidates within each K0 group, the number which have 100 % identical matches in NR, the number showing 100 % conservation with a protein in NR, the number with a 90 % identical match, and the number showing at least 90 % conservation with a protein in NR
