Haloplasma contractile is a halophilic, cell wall-less bacterium. It is the only known representative of a deep lineage, and is classified in its own family (Haloplasmataceae) and order (Haloplasmatales), in the class Mollicutes.[1] In terms of genetics, the bacterium Haloplasma contractile contains a dcw gene cluster is responsible for containing all the genes of the organism and promoting peptidoglycan synthesis. Also, MreB/Mbl are specific homologous parts of this bacterium that are vital in the contractility of the cell. Regarding its physical attributes, this organism consists of a spherical body with approximately two protrusions which alternate between straight and contracted forms.
