[Lysosomal neuraminidase, beta-galactosidase and beta-N-acetylglucosaminidase of regenerating liver tissue].
Neuraminidase (EC 3.2.1.18) beta-galactosidase (EC 3.2.1.23) and beta-N-acetylglucosaminidase (EC 3.2.1.30) were studied in normal and regenerating rat liver. All these glycosidases were shown to be predominantly localized in lysosome rich fraction. The activity of lysosomal neuraminidase in regenerating rat liver increased 24 hours after partial hepatectomy, whereas those of beta-galactosidase and beta-N-acetylglucosaminidase decreased. The presence of inhibitor of neurominidase in regenerating liver homogenate was shown. Actinomycin D and cycloheximide were shown to have no significant effect on lysosomal neuraminidase in regenerating rat liver.
