Functional Family Alpha-mannosidase

Enzyme Information

3.2.1.114
Mannosyl-oligosaccharide 1,3-1,6-alpha-mannosidase.
based on mapping to UniProt Q24451
Man(5)GlcNAc(3)-[protein] + 2 H(2)O = Man(3)GlcNAc(3)-[protein] + 2 alpha-D-mannopyranose.
-!- The enzyme, found in plants and animals, participates in the processing of N-glycans in the Golgi apparatus. -!- It removes two mannosyl residues, one linked by alpha-1,3 linkage, and the other linked by alpha-1,6 linkage, both of which are removed by the same catalytic site. -!- The enzyme is sensitive to swainsonine.
