Substrate specificities

GH130 contains phosphorylases catalyzing the phosphorolysis of β1-4mannosidic linkage at the non-reducing end of substrates. 4-O-β-D-Mannosyl-D-glucose phosphorylase (EC 2.4.1.281), β-1,4-mannooligosaccharide phosphorylase(EC 2.4.1.319), and 1,4-β-mannosyl-N-acetylglucosamine phosphorylase (EC 2.4.1.320) are members of this family.
