  1. Blast searches were performed with the characterized T. tenax enzymes or the T. acidophilum KDG kinase. The gene numbering is according to [67]. The table represents an update of recently published work referring to the phylogenetic distribution of genes involved in glucose and pentose metabolism in Archaea [13].
  2. Characterized enzymes are underlined. Abbreviations: GAD, gluconate dehydratase; KD(P)GA, 2-keto-3-deoxy-(6-phospho)-gluconate aldolase; GK II, glycerate kinases class II; KDGK, 2-keto-3-deoxygluconate kinase. EC, Enzyme Commission; COG, Clusters of Orthologous Groups. MR-MLE, mandelate racemase/muconate lactonizing enzyme subgroup of the enolase superfamily; NAL, N-acetylneuraminate lyase superfamily; MORFL, multi-organism fragment with rich leucine family; PfkB, ribokinase-like superfamily, pfkB family carbohydrate kinase; BadF/BadG/BcrA/BcrD, BadF/BadG/BcrA/BcrD ATPase family
