FunFam 22: Beta-glucosidase 11

There are 7 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.

Beta-D-glucopyranosyl abscisate beta-glucosidase. [EC: 3.2.1.175]
D-glucopyranosyl abscisate + H(2)O = D-glucose + abscisate.
  • The enzyme hydrolzes the biologically inactive beta-D-glucopyranosyl ester of abscisic acid to produce active abscisate.
  • Abscisate is a phytohormone critical for plant growth, development and adaption to various stress conditions.
  • The enzyme does not hydrolyze beta-D-glucopyranosyl zeatin.
 1 Q9SE50
Vomilenine glucosyltransferase. [EC: 2.4.1.219]
UDP-glucose + vomilenine = UDP + raucaffricine.
  • The indole alkaloid raucaffricine accumulates during the culture of Rauvolfia cell suspensions.
 1 Q9SPP9
3-alpha-(S)-strictosidine beta-glucosidase. [EC: 3.2.1.105]
Strictosidine + H(2)O = D-glucose + strictosidine aglycone.
  • Does not act on a number of closely related glycosides.
  • Strictosidine is a precursor of indole alkaloids.
 1 Q8GU20
Vicianin beta-glucosidase. [EC: 3.2.1.119]
(R)-vicianin + H(2)O = mandelonitrile + vicianose.
  • Also hydrolyzes, more slowly, (R)-amygdalin and (R)-prunasin, but not gentiobiose, linamarin or cellobiose.
 1 A2SY66
Cyanidin 3-O-glucoside 7-O-glucosyltransferase (acyl-glucose). [EC: 2.4.1.300]
1-O-vanilloyl-beta-D-glucose + cyanidin 3-O-beta-D-glucoside = vanillate + cyanidin 3,7-di-O-beta-D-glucoside.
  • Isolated from the plant Delphinium grandiflorum (delphinium).
  • Also acts on other anthocyanidins and with other acyl-glucose derivatives.
 1 E3W9M3
Raucaffricine beta-glucosidase. [EC: 3.2.1.125]
Raucaffricine + H(2)O = D-glucose + vomilenine.
  • Highly specific; some other ajmalan glucoside alkaloids are hydrolyzed, more slowly.
