EC 2.7.4.32     
Accepted name: farnesyl phosphate kinase
Reaction: CTP + (2E,6E)-farnesyl phosphate = CDP + (2E,6E)-farnesyl diphosphate
For diagram of acyclic sesquiterpenoid biosynthesis, click here
Systematic name: CTP:(2E,6E)-farnesyl-phosphate phosphotransferase
Comments: The enzyme, found in plants and animals, is specific for CTP as phosphate donor. It does not use farnesol as substrate (cf. EC 2.7.1.216, farnesol kinase).

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.

EC 2.7.4.34     
Accepted name: GDP-polyphosphate phosphotransferase
Reaction: GTP + (phosphate)n = GDP + (phosphate)n+1
Other name(s): ppk2 (gene name); polyphosphate kinase 2
Systematic name: GTP:polyphosphate phosphotransferase
Comments: Polyphosphate kinase 2, characterized from the bacterium Pseudomonas aeruginosa, uses inorganic polyphosphate as a donor to convert GDP to GTP. The enzyme can also act on ADP (cf. EC 2.7.4.1, ATP-polyphosphate phosphotransferase), but with lower activity. The enzyme has only a trivial activity in the opposite direction (synthesizing polyphosphate from GTP). The GTP that is produced is believed to be consumed by EC 2.7.7.13, mannose-1-phosphate guanylyltransferase, for production of alginate during stationary phase.
