Localization of thiamine pyrophosphatase activity in motor end plates.
, 1981 Thiamine pyrophosphatase (TPPase) activity was localized in the terminal arborization of the motor end plates both in rat and frog striated muscles. Electron microscopically the end product of the enzyme was seen in synaptic vesicles.

Membrane-bound pyrophosphatase of Thermotoga maritima requires sodium for activity
, 2005 Membrane-bound pyrophosphatase of the hyperthermophilic bacterium Thermotoga maritima(Tm-PPase), a homologue of H(+)-translocating pyrophosphatase, was expressed in Escherichia coli and isolated as inner membrane vesicles.
