α-Mannosidase (EC 3.2.1.24, α-D-mannosidase, p-nitrophenyl-α-mannosidase, α-D-mannopyranosidase, 1,2-α-mannosidase, 1,2-α-D-mannosidase, exo-α-mannosidase) is an enzyme involved in the cleavage of the α form of mannose. Its systematic name is α-D-mannoside mannohydrolase.[3][4]

Applications
It can be utilized in experiments that determine the effects of the presence or absence of mannose on specific molecules, such as recombinant proteins that are used in vaccine development.[5]
Pathology
A deficiency can lead to α-mannosidosis.[6]
