The glycosidase-recognizing N-acetylglucosamine terminal residue, N-
acetylglucosaminidase (NAG), has been repetitively implicated in fertilization. Nevertheless …

N‐acetylglucosaminidase (NAG) is particularly active in mammalian spermatozoa and
appears to be involved in fertilization. Although it is assumed that this enzyme is acrosomal …
