Both spectra showed the same intensity providing phosphate and carbonate main vibrational modes, and thus, the tested surfaces should be considered similar.
In addition, for inside-out recordings, 30 or 100 µM ATP (magnesium salt) was added freshly to the bath recording solution to prevent current rundown and to provide phosphate groups for phosphorylation in the presence of kinases.
It serves as a storage form of myo-inositol, providing phosphate and mineral nutrients for utilization during seed germination and seedling growth [ 39].
Sureka et al. [ 31] proposed that poly P could play a critical role under ATP depletion by providing phosphate for utilisation by MprAB.
It is also possible, but less likely, that acylphosphate-like protein may provide phosphate substrate for the proper function of SelD-like protein (instead of ATP).
The availability of this high-energy phosphate polymer may enhance the capacity of strain RHA1 to survive in soil environments by providing phosphate for biosynthesis, maintenance energy or an osmoprotectant.
Also, ALP gene expression represents a frequently used early marker for osteogenic differentiation, as ALP has a determinant role in the mineralization of the extracellular collagenous matrix, by providing phosphate ions that, with calcium ions, are used in the formation of the cell-mediated calcium phosphate mineralized matrix [ 20].
Later, KipI was identified as a protein inhibitor of auto-phosphorylation of kinase A, the sensor histidine kinase responsible for processing post-exponential phase information and for providing phosphate input to the phosphorelay that activates developmental transcription via phosphorylated Spo0A, and KipA as a protein that counteracts the inhibition [ 63].
The values of 0, 2 and 10 mM KH2PO4 were selected to provide phosphate-limited conditions (0 mM), an average literature value (2 mM) (Additional file 1: Table S3) and excess phosphate (10 mM) (see ' Materials and methods').
Phosphorus is present as phosphate, which provides the phosphate ion.
