ENZYME entry: EC 4.2.2.28

PURL: https://purl.expasy.org/enzyme/EC/4.2.2.28
Accepted Name
alpha-L-rhamnosyl-(1->4)-beta-D-glucuronate lyase
Alternative Name(s)
L-rhamnose-alpha-1,4-D-glucuronate lyase
Reaction catalysed
alpha-L-rhamnosyl-(1->4)-D-glucuronate = 4-deoxy-L-threo-hex-4-enopyranuronate + L-rhamnopyranose
Comment(s)
  • The enzyme, characterized from the phytopathogenic fungus Fusarium oxysporum, removes the rhamnosyl residue from alpha-L-rhamnosyl- (1->4)-beta-D-glucuronate or (with lower activity) from oligosaccharides that contain this motif at the non-reducing end, leaving an unsaturated glucuronate residue.
  • Among its natural substrates is the type II arabinogalactan component of gum arabic.
