Organism
Shigella flexneri serotype 5b (strain 8401)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Displays esterase activity towards short chain fatty esters (acyl chain length of up to 8 carbons). Able to hydrolyze triacetylglycerol (triacetin) and tributyrylglycerol (tributyrin), but not trioleylglycerol (triolein) or cholesterol oleate. Negatively regulates MalT activity by antagonizing maltotriose binding. Inhibits MelA galactosidase activity.UniRule annotation
