Venn diagram of core gene overlap of the Tannerella species. Venn diagram of core gene overlap of the Tannerella species. The presence of genes was evaluated using the “Profile and Alignment” tool on the IMG/ER website using thresholds of 50% identity and an E value of 10−5. Genes that are present in all genomes of each species were saved as a set, put into the “gene cart,” and evaluated for their presence in the genomes of the other species. Selected functional pathways that were found in the various categories are shown. NAM, N-acetylmuramic acid; AA, amino acid. Clifford J. Beall et al. mSystems 2018; doi:10.1128/mSystems.00018-18
