FunFam 4: probable beta-D-xylosidase 7

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
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.
 5 A0A178UTL8 A0A178UTL8 A5JTQ2 Q9FLG1 Q9FLG1
Non-reducing end alpha-L-arabinofuranosidase. [EC: 3.2.1.55]
Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.
  • Acts on alpha-L-arabinofuranosides, alpha-L-arabinans containing (1,3)- and/or (1,5)-linkages, arabinoxylans and arabinogalactans.
  • Some EC 3.2.1.23 and EC 3.2.1.38 enzymes also hydrolyze alpha-L- arabinosides.
  • cf. EC 3.2.1.185.
  • Formerly EC 3.2.1.79.
