amylase activity

traitmech:000162 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active amylolytic enzymes that hydrolyze starch.

Trait evidence (2)

DOI:10.3389/fbioe.2020.00871
All enzymes capable of degrading starch are collectively indicated as amylolytic enzymes.

Sidar et al. frame amylolytic enzymes as starch-degrading enzymes, grounding the organism-level phenotype as active amylase production rather than starch catabolism itself.

the Bacteroides ovatus (Bo) extracellular α-amylase, BoGH13ASus

Brown et al. characterized BoGH13A_Sus as a Bacteroides ovatus extracellular alpha-amylase in a starch utilization system, supporting B. ovatus as a source-backed amylase activity example.

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:0016160 carries the same amylase activity label but denotes the enzyme molecular function rather than the organism-level amylolytic enzyme production phenotype, so it is appropriate as a causal-node grounding rather than an equivalent TraitRecord xref.
