alpha-glucosidase activity

traitmech:000145 · CLASS · PROPOSED

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

Trait evidence (2)

DOI:10.1371/journal.pone.0322500
Enzyme activities of acid- and alkaline-phosphatases, esterase, esterase lipase, leucine arylamidase, trypsin, naphthol-AS-BI phosphohydrolase, and alpha-glucosidase are present when assayed with API ZYM system.

Park et al. treated alpha-glucosidase as a positive API ZYM enzyme-activity phenotype in the Flexibacterium corallicola type species description.
DOI:10.3390/microorganisms13092005
alkaline phosphatase, esterase (C4), lipoid esterase (C8), lipase (C14), leucine arylamines, valine arylamines, cystine arylaminase, pancreatic coagulase, acid phosphatase, naphthol-AS-BI-phosphohydrolase, alpha-glucosidase, and N-acetyl-glucosaminidase were positive

Zhang and Liu detected alpha-glucosidase in Microbulbifer weihaiensis SDUM041083T with the API ZYM enzyme activity panel.

CURATION TODO OPEN alpha-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:0090599 carries the same alpha-glucosidase activity label but denotes the enzyme molecular function rather than the organism-level alpha-glucosidase production phenotype, so it is appropriate as a causal-node grounding rather than an equivalent TraitRecord xref.
