Sysname
UDP-beta-L-rhamnose:rhamnogalacturonan I 4-rhamnosyltransferase (configuration-inverting)
Reaction(IUBMB)
UDP-beta-L-rhamnose + alpha-D-galacturonosyl-[(1->2)-alpha-L-rhamnosyl-(1->4)-alpha-D-galacturonosyl]n = UDP + [(1->2)-alpha-L-rhamnosyl-(1->4)-alpha-D-galacturonosyl]n+1 [RN:R11972]
Reaction(KEGG)
R11972
Substrate
UDP-beta-L-rhamnose [CPD:C02199];
alpha-D-galacturonosyl-[(1->2)-alpha-L-rhamnosyl-(1->4)-alpha-D-galacturonosyl]n [CPD:C21816]
Product
UDP [CPD:C00015];
[(1->2)-alpha-L-rhamnosyl-(1->4)-alpha-D-galacturonosyl]n+1
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.
