Fig. 1.
A phylogenetic tree of aldose dehydrogenase enzymes of the Gfo/Idh/MocA family. The pink branch contains L-arabinose and D-galactose dehydrogenases. The light blue branch contains bacterial and archaeal GFOR, Cc AAOR and archaeal D-xylose dehydrogenases. The orange branch contains trans-1,2-dihydrobencene-1,2-diol dehydrogenases and D-xylose dehydrogenases from higher eukaryotes. The yellow branch contains fungal sequences, including the T. reesei D-xylose dehydrogenase. Sequence names are only shown for sequences with verified or tentative E.C. number annotation in the UniProt database
