Current evidence suggests the occurrence of two classes of vacuolar-type H(+)-translocating inorganic pyrophosphatases (V-PPases): K(+)-insensitive proteins, identified in eukaryotes, bacteria and archaea, and K(+)-stimulated V-PPases, identified to date only in eukaryotes. Here, we describe the functional characterization of a thermostable V-PPase from the anaerobic hyperthermophilic bacterium Thermotoga maritima by heterologous expression in Saccharomyces cerevisiae. The activity of this 71… CONTINUE READING
