Description

Biochem/physiol Actions

Cleaves α(1→3)- and α(1→6)-linked, non-reducing terminal galactose from complex carbohydrates and glycoproteins. It is particularly efficient for removing α-linked galactose under conditions where the pH must be neutral or above, for example, with live cells.

Unit Definition

One unit will hydrolyze 1 μmole of p-nitrophenyl α-D-galactopyranoside per min at pH 6.5 at 25 °C.
