<p align="justify">Lon proteins are grouped into two families, '''LonA''' and '''LonB'''. The human protein LonP1 is part of the LonA proteins <ref>« The N-terminal domain plays a crucial role in the structure of a full-length human mitochondrial Lon protease | Scientific Reports ».

Globally there is a great diversity of Lon proteins, but they are all organized in an oligomeric ring structure, mostly hexameric structure with identical subunits. | Globally there is a great diversity of Lon proteins, but they are all organized 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 to yeast [https://www.yeastgenome.org/locus/S000000118 Pim1] ) | Lon proteins are therefore an hexameric chambered [https://en.wikipedia.org/wiki/Protease protease] complex.
