This would only require the phosphoryl oxygens of the bound ADP intermediate be capable of undergoing positional isotope exchange, depending on a symmetrical torsional motion before returning to

The combined efforts of some excellent graduate students and postdocs, most of whom went on to rewarding academic careers, culminated in the discovery of a new type of phosphorylated protein, a catalytic intermediate in ATP formation with a phosphoryl group attached to a histidine residue.
-
He left this post to explore the chemical nature of some seemingly unusual phosphate derivatives arising in the process of group activation through phosphoryl transfer from ATP.
-
The distances between P-sites and the γ-phosphate of ATP (Table 2) argue against large conformational changes at the subunit interface for phosphoryl transfer.

Hydrogen bonds are blue, activation of T432 and S431 by E318 as well as phosphoryl transfers are indicated by red arrows, and a wiggly red arrow implies phosphatase activity. doi: 10.1371/journal. pone.0007529.g008

We believe that the presence of Ala rather than Thr or Ser at this site is to rule out a phosphoryl transfer in the CI half, thus limiting the roles of the N-terminal KaiC ring to catalyze ATP hydrolysis and serve as a structural platform.

Cohen and coworkers achieve this control by coating quantum dots with dithiolate ligands connected to ortho-nitrobenzyl (ONB) groups through a phosphoryl linker.
