Mechanism summary

Mode of action: MEMBRANE_DISRUPTION host shared target — Assigned from ChEBI role CHEBI:24869 (ionophore). ChEBI asserts the role on the compound. The target it names is one the host has too, so the mechanism is true but is not evidence of selectivity — see mode_of_action_target_scope. Not a curator's mechanistic review.
