GH38 enzymes are Class II &alpha;-mannosidases. They range in breadth of specificity from the Golgi &alpha;-mannosidase (2A1), which has a dual specificity for &alpha;1,6 and &alpha;1,3-linked mannoses, to the lysosomal mannosidases, which have either broad (2B1 cleaves &alpha;1,2, &alpha;1,3 and &alpha;1,6 linkages) or narrow specificities (2B2 is specific for &alpha;1,6).

Substrate specificities

GH38 enzymes are Class II α-mannosidases. They range in breadth of specificity from the Golgi α-mannosidase (2A1), which has a dual specificity for α1,6 and α1,3-linked mannoses, to the lysosomal mannosidases, which have either broad (2B1 cleaves α1,2, α1,3 and α1,6 linkages) or narrow specificities (2B2 is specific for α1,6).
