Figure 3.

The enhanced representation of UDP-d-xylose biosynthesis pathway in prototype P. trichocarpa PGDB. In this representation the sub-cellular localization of each metabolite in the pathway is specified by a two-letter prefix (Table 3). Note that Figure 2 shows 12 genes annotated as UDP-glucose dehydrogenases and 9 genes annotated as UDP-glucuronate decarboxylase. Manual curation yields only four UDP-glucose dehydrogenase enzymes and six UDP-glucuronate decarboxylase enzymes in Populus. Also note that genes encoding Golgi-localized membrane-bound UDP-glucuronic acid decarboxylase (UXS) can now be distinguished from the same enzyme activity residing in the cytosol.
