ENZYME entry: EC 3.2.1.152

Accepted Name
Mannosylglycoprotein endo-beta-mannosidase.
Alternative Name(s)
Endo-beta-mannosidase.
Reaction catalysed
Hydrolysis of the alpha-D-mannosyl-(1->6)-beta-D-mannosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl sequence of glycoprotein to alpha-D-mannosyl-(1->6)-D-mannose and N-acetyl-beta-D-glucosaminyl-(1->4)-N-acetyl-beta-D-glucosaminyl sequences
Comment(s)
  • The substrate group is a substituent on N-4 of an asparagine residue in the glycoprotein.
  • The mannose residue at the non-reducing end of the sequence may carry further alpha-D-mannosyl groups on O-3 or O-6, but such a substituent on O-3 of the beta-D-mannosyl group prevents the action of the enzyme.
  • The enzyme was obtained from the lily, Lilium longiflorum.
