FunFam 41: Beta-glucosidase 7

There are 6 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.

4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl glucoside beta-D-glucosidase. [EC: 3.2.1.182]
(1) (2R)-4-hydroxy-7-methoxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D-glucopyranoside + H(2)O = 2,4-dihydroxy-7-methoxy-2H-1,4- benzoxazin-3(4H)-one + D-glucose. (2) (2R)-4-hydroxy-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-2-yl beta-D- glucopyranoside + H(2)O = 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one + D-glucose.
  • The enzyme from Triticum aestivum (wheat) has a higher affinity for DIMBOA glucoside than DIBOA glucoside.
  • With Secale cereale (rye) the preference is reversed.
 5 P49235 P49235 Q41761 Q53WW9 Q53WW9
Avenacosidase. [EC: 3.2.1.188]
Avenacoside B + H(2)O = 26-desgluco-avenacoside B + D-glucose.
  • Isolated from oat (Avena sativa) seedlings.
  • The product acts as a defense system against fungal infection.
  • Also acts on avenacoside A.
 2 Q38786 Q9ZP27
Oleuropein beta-glucosidase. [EC: 3.2.1.206]
Oleuropein + H(2)O = oleuropein aglycone + D-glucopyranose.
  • Oleuropein is a glycosylated secoiridoid exclusively biosynthesized by members of the Oleaceae plant family where it is part of a defense system againt herbivores.
  • The enzyme also hydrolyzes ligstroside and demethyloleuropein.
 1 Q8GVD0
Coniferin beta-glucosidase. [EC: 3.2.1.126]
Coniferin + H(2)O = D-glucose + coniferol.
  • Also hydrolyzes syringin, 4-cinnamyl alcohol beta-glucoside and, more slowly, some other aryl beta-glycosides.
  • A plant cell-wall enzyme involved in the biosynthesis of lignin.
