Common Hydrogen Bond Interactions in Diverse Phosphoryl Transfer Active Sites
Figure 6
The O3β—Pγ bond length and hyperconjugation increase with decreasing D•••O3β hydrogen bond length in Structure1.
Calculated E(2) energy is of the n(Oγ)→σ*(O3β—Pγ) hyperconjugative interaction. D is the N—H hydrogen bond donor in N-methylacetamide.
