Alpha-L-fucosidase from bull seminal plasma: its purification and acrosome reaction promoting property.
Alpha-L-fucosidase was purified from the bull seminal plasma by chromatography on DEAE-disk, octyl sepharose hydrophobic column and HPLC. The enzyme appeared to be pure as judged by the polyacrylamide gel electrophoresis both under the nondenaturing and denaturing conditions. The pure enzyme promoted the acrosome reaction of guinea pig spermatozoa in vitro. This is the first report showing that an acrosomal enzyme induces acrosome reaction which is an essential pre-requisite for the gamete interaction and fertilization.
