Fig. 4From: A comprehensive survey of integron-associated genes present in metagenomesGene ontology analysis of the integron-associated genes using PFAM families. Out of the 13,397 integron-associated genes in our catalog, 3,488 matched a PFAM family with a known function, which were in turn mapped to the metagenomics GO slim. Not all PFAM families mapped to a GO term; as a result, 1534 genes had a corresponding GO term. Level 1 terms were removed and those with at least 5 counts were kept (For the whole list GO terms and their counts please see Additional file 3: Table S2)Back to article page
