Functioni

By generating PPi, plays a role in regulating pyrophosphate levels, and functions in bone mineralization and soft tissue calcification. PPi inhibits mineralization by binding to nascent hydroxyapatite (HA) crystals, thereby preventing further growth of these crystals. Preferentially hydrolyzes ATP, but can also hydrolyze other nucleoside 5' triphosphates such as GTP, CTP, TTP and UTP to their corresponding monophosphates with release of pyrophosphate and diadenosine polyphosphates, and also 3',5'-cAMP to AMP. May also be involved in the regulation of the availability of nucleotide sugars in the endoplasmic reticulum and Golgi, and the regulation of purinergic signaling. Appears to modulate insulin sensitivity and function.3 Publications

Caution

It is uncertain whether Met-1 or Met-53 is the initiator.Curated

Catalytic activityi

Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.1 Publication
A nucleoside triphosphate + H2O = a nucleotide + diphosphate.1 Publication

Cofactori

Zn2+By similarityNote: Binds 2 Zn2+ ions per subunit.By similarity

Enzyme regulationi

At low concentrations of ATP, a phosphorylated intermediate is formed which inhibits further hydrolysis.

Cole disease (COLED)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA rare autosomal dominant genodermatosis characterized by punctate keratoderma associated with irregularly shaped hypopigmented macules, which are typically found over the arms and legs but not the trunk or acral regions. Skin biopsies of palmoplantar lesions show hyperorthokeratosis, hypergranulosis, and acanthosis. Hypopigmented areas of skin, however, reveal a reduction in melanin content in keratinocytes but not in melanocytes, as well as hyperkeratosis and a normal number of melanocytes. Ultrastructurally, melanocytes show a disproportionately large number of melanosomes in the cytoplasm and dendrites, whereas keratinocytes show a paucity of these organelles, suggestive of impaired melanosome transfer. Some patients also exhibit calcinosis cutis or calcific tendinopathy.
