inorganic diphosphatase M-CSA #916 | Soluble inorganic pyrophosphate is present in all organisms, and is essential for cell growth. It provides an entropic pull for biosynthetic reactions involving nucleotide triphosphates by irreversibly hydrolysing the pyrophosphate product to orthophosphate. The phosphoryltransferase activity is an ancient one, and there are functional similarities between the active site of this enzyme and alkaline phosphatase and other divalent cation containing enzymes such as exonucleases and polymerases. | Defined by 6 residues: GLU:A-17 [auth A-8]TYR:A-51 [auth A-42]ASP:A-61 [auth A-52]ASP:A-66 [auth A-57]ASP:A-93 [auth A-84]ASP:A-98 [auth A-89] | EC: 3.6.1.1 (PDB Primary Data) |
