Inorganic pyrophosphatase [EC 3.6.1.1] isolated from rat sublingual and submandibular glands was purified 2300-fold and 2600-fold, respectively. The purified enzymatic preparations separated on electrophoresis into two protein bands, of which only one showed the pyrophosphatase activity. Inorganic pyrophosphatase from rat salivary glands is a monomeric anionic protein, its isoelectric point is 5.42 and 4.90 for the sublingual and submandibular glands, respectively.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013361	Sublingual Gland	A salivary gland on each side of the mouth below the TONGUE.	Gland, Sublingual,Glands, Sublingual,Sublingual Glands
D013363	Submandibular Gland	One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur.

D043564	Inorganic Pyrophosphatase	An enzyme which catalyzes the hydrolysis of diphosphate (DIPHOSPHATES) into inorganic phosphate. The hydrolysis of pyrophosphate is coupled to the transport of HYDROGEN IONS across a membrane.
