| galactosidase | <enzyme> One of a class of enzymes which cuts the glycosidic bond between the sugar galactose and another sugar molecule (of a different type than galactose). There are two subclasses - the alpha galactosidases and beta galactosidases - which cuts the two types of glycosidic bonds (alpha and beta, respectively). (09 Oct 1997) |
