alpha-Mannosidase (EC 3.2.1.24, alpha-D-mannosidase, p-nitrophenyl-alpha-mannosidase, alpha-D-mannopyranosidase, 1,2-alpha-mannosidase, 1,2-alpha-D-mannosidase, exo-alpha-mannosidase) is an enzyme involved in the cleavage of the alpha form of mannose. Its systematic name is alpha-D-mannoside mannohydrolase.[3][4]
Isozymes[edit]
Humans express the following three alpha-mannosidase isozymes:

Applications[edit]
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[edit]
A deficiency can lead to alpha-mannosidosis.[6]
