EC 2.7.4.33     
Accepted name: AMP-polyphosphate phosphotransferase
Reaction: ADP + (phosphate)n = AMP + (phosphate)n+1
Other name(s): PA3455 (locus name); PPK2D; PAP
Systematic name: ADP:polyphosphate phosphotransferase
Comments: The enzyme, characterized from the bacteria Acinetobacter johnsonii and Pseudomonas aeruginosa, transfers a phosphate group from polyphosphates to nucleotide monophosphates. The highest activity is achieved with AMP, but the enzyme can also phosphorylate GMP, dAMP, dGMP, IMP, and XMP. The reverse reactions were not detected.
