Other Notes A homohexameric protein containing 175 amino acid residues per subunit, its activity is Mg2+ dependent. It is a relatively thermostable protein.
Unit Definition One unit will release 1.0 μmole of inorganic orthophosphate per minute at pH 9 at 25 °C.
Physical form Lyophilized powder in Tris-buffered salts containing protease inhibitors
Application Inorganic pyrophosphatase (PPase) is a ubiquitous enzyme catalyzing the reaction PPi + H2O → 2Pi.
It plays an important role in protein, RNA, and DNA synthesis.
