Correction: The new world of inorganic polyphosphates.

Optimizing the production of Polyphosphate from Acinetobacter towneri

Inorganic polyphosphates (PolyP) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. Four isolates had been screened from soil sample. By MALDI-TOF analysis, they were identified as Bacillius cereus, Acinetobacter towneri, B. megaterium and B. cereus. The production of PolyP in four isolates was studied in phosph...

Inorganic polyphosphate in the microbial world. Emerging roles for a multifaceted biopolymer.

Inorganic polyphosphates (polyP) are linear polymers of tens to hundreds orthophosphate residues linked by phosphoanhydride bonds. These fairly abundant biopolymers occur in all extant forms of life, from prokaryotes to mammals, and could have played a relevant role in prebiotic evolution. Since the first identification of polyP deposits as metachromatic or volutin granules in yeasts in the nin...

31P NMR spectroscopy of Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major. Evidence for high levels of condensed inorganic phosphates.

High resolution (31)P nuclear magnetic resonance spectra at 303.6 MHz (corresponding to a (1)H resonance frequency of 750 MHz) have been obtained of perchloric acid extracts of Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major, the causative agents of African sleeping sickness, Chagas' disease, and leishmaniasis. Essentially complete assignments have been made based on chemical shifts...

Synthesis and Evaluation of Chromogenic and Fluorogenic Substrates for High-Throughput Detection of Enzymes That Hydrolyze Inorganic Polyphosphate

Inorganic polyphosphates, linear polymers of orthophosphate, occur naturally throughout biology and have many industrial applications. Their biodegradable nature makes them attractive for a multitude of uses, and it would be important to understand how polyphosphates are turned over enzymatically. Studies of inorganic polyphosphatases are, however, hampered by the lack of high-throughput method...
