Pentosyltransferases
BRITE hierarchy
Sysname
UDP-D-xylose:xylogalacturonan 3-beta-D-xylosyltransferase
Reaction(IUBMB)
Transfers a xylosyl residue from UDP-D-xylose to a D-galactose residue in xylogalacturonan, forming a beta-1,3-D-xylosyl-D-galactose linkage.
Comment
Involved in plant cell wall synthesis. The enzyme from Arabidopsis thaliana also transfers D-xylose from UDP-D-xylose onto oligogalacturonide acceptors. The enzyme did not show significant activity with UDP-glucose, UDP-galactose, or UDP-N-acetyl-D-glucosamine as sugar donors.
