Here, we report the draft genome sequence of Sphingorhabdus sp. strain EL138, an alphaproteobacterium that shows potential to degrade polycyclic aromatic compounds and to cope with various heavy metals and antibiotics. Moreover, the strain, isolated from the gorgonian coral Eunicella labiata, possesses several genes involved in the biosynthesis of polyphosphates, polyketides, and terpenoids.

Ins(3,4,5,6)P(4) is an inhibitor of Ca(2+)-activated Cl(-) channels, but further understanding has been hindered by ignorance of how it is made in cells. It now transpires that one protein with ATP-dependent kinase and phosphatase activities interconverts Ins(3,4,5,6)P(4) and Ins(1,3,4,5,6)P(5), as well as several other inositol polyphosphates.

In tundra, phosphorus (P) is an important macronutrient for plants and microorganisms. A major fraction of P exists as organic compounds in the topsoil which can be mineralized to bioavailable inorganic P. Since mineralization is positively related to temperature, climate warming is likely to increase P bioavailability but the extend of these changes may also depend on vegetation cover and soil...

Figure 1 Model of two independent PTMs, serine-pyrophosphorylation and lysine-polyphosphorylation Protein pyrophosphorylation is the transfer of the b-phosphate group of the pyrophosphate moiety of IP7 on to a pre-phosphorylated serine residue (left) [16,17]. Conversely, protein polyphosphorylation is the covalent attachment of a chain of inorganic polyP on to a lysine residue dependent on the ...

Chromatin remodeling is required for efficient transcription of eukaryotic genes. In a genetic selection for budding yeast mutants that were defective in induction of the phosphate-responsive PHO5 gene, we identified mutations in ARG82/IPK2, which encodes a nuclear inositol polyphosphate kinase. In arg82 mutant strains, remodeling of PHO5 promoter chromatin is impaired, and the adenosine tripho...

Electrospray ionization mass spectrometry (ESI-MS) was applied for the characterization of inorganic polyphosphates [orthophosphate, pyrophosphate, tripolyphosphate, trimetaphosphate, and tetrapolyphosphatel. The high selectivity of ESI-MS allows the detection of different polyphosphate species without preseparation by ion chromatography or capillary electrophoresis. Furthermore, ESI-MS does no...
