Phosphate transfer from inositol pyrophosphates InsP5PP and InsP4(PP)2: A semi-empirical investigation
Graphical abstract
PM3/SM5.2 semi-empirical calculations were used to calculate the free energy of phosphate transfer from InsP5PP and InsP4(PP)2 to methanol as a model system for non-enzymatic phosphorylation of protein residues by these intracellular pyrophosphates.

IP8: A quantitatively minor inositol pyrophosphate signaling molecule that punches above its weight

2021, Encyclopedia of Biological Chemistry: Third EditionA high energy phosphate jump - From pyrophospho-inositol to pyrophospho-serine
2020, Advances in Biological RegulationCitation Excerpt :However, electrostatic and steric repulsion from adjacent monophosphates is likely to increase the thermodynamic favourability of β-phosphate release (Hand and Honek, 2007). Indeed, this phosphate release is expected to be strongly exothermic, with semi-empirical calculations revealing that the free enthalpy (ΔH) for transfer of the β-phosphate from 5-IP7 to methanol can reach −38.3 kcal/mol at pH 6.8 (Hand and Honek, 2007). As discussed above, during the pyrophosphorylation reaction, the Asp/Glu-rich disordered substrate peptide must associate with the Mg2+-IP7 complex via coordinate bond formation.
Dynamics of Substrate Processing by PPIP5K2, a Versatile Catalytic Machine
2019, StructureCitation Excerpt :The X-ray structure of PPIP5K2 in complex with ADP and 1,5-IP8 (PDB: 4Q4C) was used to build the starting configuration for eight independent MD runs (1 μs each). The activation barrier for hydrolysis of the 1-β-phosphate of IP8 is not known, although it is generally considered to be less than that for ATP (Hand and Honek, 2007). Indeed, the ability of PP-IPs to pyrophosphorylate proteins by a mechanism that is entirely chemical in nature is consistent with a low activation barrier for their phosphoanhydride bond cleavage (Saiardi et al., 2004).
Inositol phosphate kinases: Expanding the biological significance of the universal core of the protein kinase fold
2019, Advances in Biological RegulationCitation Excerpt :As for IP6Ks, these are of particular interest because they add a 5-β-phosphate to InsP6, yielding 5-InsP7, an ‘inositol pyrophosphate’ (Saiardi et al., 1999; Shears, 2017). The latter is an ‘energetic’ (Hand and Honek, 2007), multifunctional molecule that receives particular attention for its key roles in bioenergetic homeostasis, cancer, and aging (Chakraborty, 2017; Shears, 2017). Bearing in mind the enormous significance of the PDKG-InsPK family, it is unsurprising that several groups have taken a structural approach to characterizing these enzymes (Bennett et al., 2006; Chamberlain et al., 2005; Endo-Streeter et al., 2012; Gonzalez et al., 2004; Holmes and Jogl, 2006; Miller and Hurley, 2004; Wang et al., 2014; Wang and Shears, 2017).
The significance of the 1-kinase/1-phosphatase activities of the PPIP5K family
2017, Advances in Biological RegulationCitation Excerpt :Inositol pyrophosphates (PP-InsPs; Fig. 1) are a specialized class of cell signaling molecules that boast a unique, functionally significant feature: the most crowded three-dimensional arrangement of phosphate groups that has been observed throughout Nature. Crammed around a six-carbon inositol scaffold are as many as seven or eight phosphates (for “InsP7” and “InsP8” respectively, see Fig. 1), including diphosphate groups that are highly ‘energetic’ (Hand and Honek, 2007; Shears, 2015). Yeasts and metazoan cells can phosphorylate InsP6 to InsP8 through two parallel pathways (Fig. 1), which utilize two separate classes of enzymes to form diphosphate groups: the 5-kinases (the IP6Ks (E.C.2.7.4.21); Draskovic et al., 2008; Saiardi et al., 1999) and the 1-kinases (the PPIP5Ks (E.C. 2.7.4.24); Lin et al., 2009; Wang et al., 2012).
