show Brenda entryEC number
2.4.1.351
Accepted name
rhamnogalacturonan I rhamnosyltransferase
Reaction
UDP-β-L-rhamnose + α-D-galacturonosyl-[(1→2)-α-L-rhamnosyl-(1→4)-α-D-galacturonosyl]n = UDP + [(1→2)-α-L-rhamnosyl-(1→4)-α-D-galacturonosyl]n+1
Other name(s)
RRT,
RG I rhamnosyltransferase
Systematic name
UDP-β-L-rhamnose:rhamnogalacturonan I 4-rhamnosyltransferase (configuration-inverting)
Comment
The enzyme, characterized from Vigna angularis (azuki beans), participates in the biosynthesis of rhamnogalacturonan type I. It does not require any metal ions, and prefers substrates with a degree of polymerization larger than 7.
