FunFam 4141: Cel3e putative secreted beta-glucosidase

There are 4 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
Beta-glucosidase. [EC: 3.2.1.21]
Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose.
  • Wide specificity for beta-D-glucosides.
  • Some examples also hydrolyze one or more of the following: beta-D- galactosides, alpha-L-arabinosides, beta-D-xylosides and beta-D- fucosides.

Glucan 1,4-beta-glucosidase. [EC: 3.2.1.74]
Hydrolysis of (1->4)-linkages in (1->4)-beta-D-glucans, to remove successive glucose units.
  • Acts on 1,4-beta-D-glucans and related oligosaccharides.
  • Cellobiose is hydrolyzed, but very slowly.

Xylan 1,4-beta-xylosidase. [EC: 3.2.1.37]
Hydrolysis of (1->4)-beta-D-xylans, to remove successive D-xylose residues from the non-reducing termini.
  • Also hydrolyzes xylobiose.
  • Some other exoglycosidase activities have been found associated with this enzyme in sheep liver.
2 A0A174CI30 D2Q5N4
Alpha-galactosidase. [EC: 3.2.1.22]
Hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha- D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids.
  • Also hydrolyzes alpha-D-fucosides.
