  • 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

    Irwin Rose - Autobiography

  • 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.

    Paul D. Boyer - Autobiography

  • 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.

    Fritz Lipmann - Biography

  • 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.

  • Both the E318A and E318D mutants are arhythmic and the former lacks the ability for phosphoryl transfer judging from SDS-PAGE gels (
