DE   rhamnogalacturonan I galactosyltransferase.
CA   Transfer of a beta-galactosyl residue in a beta-(1->4) linkage from UDP-
CA   alpha-D-galactose to rhamnosyl residues within the rhamnogalacturonan I
CA   backbone.
CC   -!- The enzyme, characterized from the plant Vigna angularis (azuki
CC       beans), participates in the biosynthesis of rhamnogalacturonan I,
CC       one of the components of pectin in plant cell wall.
CC   -!- It does not require any metal ions, and prefers substrates with a
CC       degree of polymerization larger than 9.
