Abstract
This invention relates to a novel polyphosphate: AMP phosphotransferase (PAP), a gene coding this PAP, and their use. The PAP has the following properties: (A) action: catalyzing of the following two reactions:NMP+PolyP→NDP+PolyPdNMP+POlyP→dNDP+PolyP(wherein NMP represents nucleoside monophosphate, NDP represents nucleoside diphosphate, dNMP represents deoxynucleoside monophosphate, dNDP represents deoxynucleoside diphosphate, n represents degree of polymerization of the polyphosphate which is an integer of up to 100); (B) substrate specificity: specific to AMP, GMP, IMP, dAMP, and dGMP, also acting with CMP, UMP, dCMP, and TMP; (C) molecular weight: about 55 to 56 Kd (kilodalton); and (D) specific activity: at least 70 units per 1 mg of enzyme protein.
