Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
evolution
the enzyme is a member of the UGlcAE family, a subfamily of the the SDR enzyme superfamily. The only three family members are OcUGlcAE1, OcUGlcAE2, and OcUGlcAE3, isolated from Ornithogalum caudatum. Phylogenetic relationships of OcUGlcAE with other UGlcAE, UGE (UDP-D-glucose 4-epimerase) and UXE (UDP-D-xylose 4-epimerase) enzymes are analyzed
malfunction
deletion of the conversed GxxGxxG motif result in the activity loss of OcUGlcAE3
physiological function
additional information
-
GAE delivers the main substrate for pectin biosynthesis
physiological function
-
GAE is necessary for Arabidopsis root hair growth
physiological function
UDP-D-glucuronic acid 4-epimerase OcUGlcAE3 is involved in the biosynthesis of root polysaccharides
the N-terminus of UGlcAEs plays important roles in their soluble expression and 4-epimerase activity
