Many transcripts are involved in “DNA integration” including transposon integration perhaps mediated by “nucleic acid phosphodiester bond hydrolysis,” another enriched GO. WebPhosphorylation requires a phosphate source of course, but also an energy source, because forming P-O bonds is not a favorable reaction on its own (the reverse of the above). So adding a lone phosphate would not be favorable, but transfering one from ATP is much better, because this simultaneously involves breaking a P-O bond in ATP, "freeing ... crystal altland
