Figure 1: A partial list of plant NDP-sugars and interconversion enzymes.

Figure 1:

Eleven NDP-sugars and enzyme families involved in building plant cell wall polysaccharides are indicated. Polysaccharides in which NDP-sugars may be incorporated are indicated beside the respective NDP-sugar, underlined and italicized. Reactions are shown as arrows, and enzymes are indicated in bold beside the arrows. Abbreviations: UAXS (UDP-D-apiose/UDP-D-xylose synthase, also known as AXS), UGlcAE (UDP-D-glucuronic acid 4-epimerase, also know as GAE), GER (GDP-4-keto-6-deoxy-D-mannose-3,5-epimerase-4-reductase), GMD (GDP-D-mannose-4,6-dehydratase), GME (GDP-D-mannose 3,5-epimerase), RHM (UDP-L-rhamnose synthase), NRS/ER (nucleotide-rhamnose synthase/epimerase-reductase, also known as UER), UGD (UDP-D-glucose dehydrogenase), UGE (UDP-D-glucose 4-epimerase), UXE (UDP-D-xylose 4-epimerase) and UXS (UDP-D-xylose synthase, including AUD [membrane-anchored UXS] and SUD [soluble UXS]).
