Some proteins in this family, annotated as endo-alpha-mannosidases cleave mannoside linkages internally within an N-linked glycan chain, short circuiting the classical N-glycan biosynthetic pathway. This domain reveals a (beta-alpha)(8) barrel fold in which the catalytic centre is present in a long substrate-binding groove, consistent with cleavage within the N-glycan chain, providing a foundation upon which to develop new enzyme inhibitors targeting the hijacking of N-glycan synthesis in viral disease and cancer [1].
