Globally there is a great diversity of Lon proteins, but they are all organised in an oligomeric ring structure, mostly hexameric structure with identical subunits.

Lon proteins are therefore an hexameric chambered [https://en.wikipedia.org/wiki/Protease protease] complex. (This structure is similar with yeast [https://www.yeastgenome.org/locus/S000000118 Pim1] )

The six Lon monomers are forming three pairs of legs owned by the N-terminal domain of the protein. This structure is emerging of the protein as a trimer of dimers.

Like many proteins, Lon is a '''flexible''' peptide which has different '''three-dimensional conformations'''.  The protein can therefore pass from one conformation to another by hydrolysis of [https://biologydictionary.net/atp/ ATP].
