beta-glucosidase activity

traitmech:000146 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active beta-glucosidase enzymes that hydrolyze beta-D-glucosidic bonds in beta-D-glucosides.

  • DOI:10.1007/s13205-015-0328-z
    β-Glucosidases (β-d-glucopyrranoside glucohydrolase) [E.C.3.2.1.21] are the enzymes which hydrolyze the glycosidic bond of a carbohydrate moiety to release nonreducing terminal glycosyl residues, glycoside and oligosaccharides

    The review defines beta-glucosidases as EC 3.2.1.21 glycoside hydrolases, grounding the enzyme activity named by the organism-level phenotype.

  • DOI:10.2323/jgam.60.59
    In API ZYM, activities are positive for alkaline phosphatase, esterase (C4), leucine arylamidase, valine arylamidase, cystine arylamidase, acid phosphatase, naphthol-AS-BI-phosphohydrolase, α-glucosidase, β-glucosidase

    The Flavobacterium panaciterrae species description reports beta-glucosidase among positive API ZYM activities for the DCY69T type strain.

  • DOI:10.3390/microorganisms12040776
    Although both strains showed positive results for α-glucosidase activity, β-glucosidase activity was only observed in L. mucosae NK41.

    Ma et al. detected beta-glucosidase activity in Limosilactobacillus mucosae NK41 with the API ZYM enzyme activity panel.

CURATION TODO OPEN beta-glucosidase-activity-xref-gap · raised by codex · 2026-09-11

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

GO:0008422 denotes the beta-D-glucosidase molecular function rather than the organism-level beta-glucosidase production phenotype, so it belongs as a causal-node grounding when a mechanistic graph needs the catalytic activity but not as an equivalent TraitRecord xref.
