lecithinase activity

traitmech:000140 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active lecithinases that hydrolyze lecithin or phosphatidylcholine.

Trait evidence (2)

  • DOI:10.2147/IDR.S365254
    all tested isolates were positive for lecithinase reaction and showed opaque zone around colonies on egg yolk agar

    Algammal et al. used an egg-yolk agar lecithinase reaction to phenotype Bacillus cereus isolates.

  • DOI:10.1128/jb.81.6.939-945.1961
    egg yolk were used for the demonstration of lecithinase activity

    Esselmann and Liu surveyed lecithinase production by Gram-negative bacteria on egg-yolk agar.

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:0004629 denotes C-type glycerophospholipase molecular function rather than the organism-level lecithinase production phenotype, so it is too scope-shifted for an equivalent TraitRecord xref.
