| 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) |
| Comments: |
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. |
