Enniatin

Enniatins are a class of organic chemical compounds found in Fusarium fungi. They appear in nature as mixtures of cyclic depsipeptides. The main variants are enniatin A, A1, B and B1 together with minor amounts of enniatin C, D, E and F.

The enniatins act as ionophores that bind ammonium, and they have been proposed as replacements for nonactin in specific ammonium-based electrodes.
