FunFam 117: Lactase

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Glycosylceramidase. [EC: 3.2.1.62]
Glycosyl-N-acylsphingosine + H(2)O = N-acylsphingosine + a sugar.
  • Broad specificity (cf. EC 3.2.1.45 and EC 3.2.1.46).
  • Also hydrolyzes phlorizin to phloretin and glucose.
  • The intestinal enzyme is a complex which also catalyzes the reaction of EC 3.2.1.108.
 2 P09848 Q02401
Lactase. [EC: 3.2.1.108]
Lactose + H(2)O = D-galactose + D-glucose.
  • The enzyme from intestinal mucosa is isolated as a complex which also catalyzes the reaction of EC 3.2.1.62 (cf. EC 3.2.1.23).
