|Abstract:||Pyrophosphatase (PPase), is an enzyme which catalyzes the hydrolysis of inorganic pyrophosphate (PPi) to organic phosphate (Pi). The relative high energy of hydrolysis (ΔG’˚) indicates that the reaction is thermodynamically irreversible. At equilibrium the reaction mixture will consist predominantly of Pi (K = 1.26 x 10-6). Many enzyme-catalyzed reactions occurring in subcellular particles produce PPi as one of their reaction products, for example ATP hydrolysis in microsomal preparation (Kennery et al, 1957) and fatty acid activation in mitochondria (Mahler, 1952) (Equation 1). In addition, PPi is formed during protein synthesis at the stage of amino acid activation (Equation 2) (Hoagland et al, 1956), during nucleic acid synthesis at the polymerization step (Kornberg, 1960) and in polysaccharide interconversion during the formation of a glycosyl donor (Leloir & Cardini, 1957).|
