D Galactoside Binding Lectin

A class of Animal Lectins that bind specifically to beta-galactoside in a Calcium-independent manner. Members of this class are distiguished from other Lectins by the presence of a conserved carbohydrate recognition domain. The majority of Proteins in this class bind to sugar molecules in a sulfhydryl-dependent manner and are often referred to as S-type Lectins, however this property is not required for membership in this class.
