The wrong version of Figure 1 was published in this article; the correct version is presented here. In the original Figure 1 the phosphoramidate was improperly represented with a phosphate linked to the oxygen group. The correct bond is P-N.
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 hydrolysis of an internal phosphate ester linkage (right) [1].](https://port.silverchair-cdn.com/port/content_public/journal/biochemsoctrans/44/4/10.1042_bst0441183a/3/m_bst0441183afig1.jpeg?Expires=1716531862&Signature=0KPGXHlVJ-mZVGEJBmIMpN7xUZMo57~0PZRlFgh6Y-hVjRnLNMhyt3fpJXBcnzju9X1g-bCroYGFeDmRTbavE-3474XE0FOwEMefMsXPmCeVklTKcA4F8iZGPjB4tw3l4q9YY0DPfGnTIR3Q3KLWWWBI0LfzXF65u7hMqOve~5gJ-UCSMjDBTC8mRNnriBs2XNCWeiF-U-E-1OL4XYJeUHW0sAm9mhtydtEA~vVU6~3O1NEMZ~SkQ1bR17w-dHTTxQ8klDPy3Z5t2PVbc8vFw-R08jC2tK9W2sb1vAjmwTY-PF7AsnJ6wrXZOcfxPC2vJ-lGEOXBk9r8xDMqUpY0uw__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
