Non-complementary negative electrostatic surface potential of protein sites specific for anions
Hodel, A. E. and Quiocho, F. A.  International Tables for Crystallography (2012). Vol. F, Section 23.3.5.3, p. 763 [ doi:10.1107/97809553602060000892 ]
... an anion-binding site, as observed in PBP. In fact, a related discovery of profound ramification is that the binding-cleft ... al., 1996). Non-complementarity between the surface potential of a binding region and an anion ligand is not unique to PBP. We have reported similar findings for SBP, a DNA-binding protein, and, even more dramatically, for the ...

Short hydrogen bonds
Hodel, A. E. and Quiocho, F. A.  International Tables for Crystallography (2012). Vol. F, Section 23.3.5.2, p. 763 [ doi:10.1107/97809553602060000892 ]
... has been assessed to be no better than that of a normal hydrogen bond (Wang et al., 1997). Thus, a unique role for short hydrogen bonds in biological systems, such ... bonds and enzymic catalysis. Science, 264, 1887-1890. Gerlt, J. A. & Gassman, P. G. (1993). Understanding the rates of ...

Dominant role of local dipoles in stabilization of isolated charges
Hodel, A. E. and Quiocho, F. A.  International Tables for Crystallography (2012). Vol. F, Section 23.3.5.1, p. 762 [ doi:10.1107/97809553602060000892 ]
... Dominant role of local dipoles in stabilization of isolated charges A novel finding of further paramount importance and wide implication is ... are associated with the sulfate completely buried in SBP. Although a salt link involving Arg135 is formed with the phosphate bound ... salt link (Yao et al., 1996). These findings are a powerful demonstration of how a protein is able to ...

Phosphate and sulfate
Hodel, A. E. and Quiocho, F. A.  International Tables for Crystallography (2012). Vol. F, Section 23.3.5, pp. 761-763 [ doi:10.1107/97809553602060000892 ]
... no overlap in specificity (Medveczky & Rosenberg, 1971; Pardee, 1966; Jacobson & Quiocho, 1988). This stringent specificity prevents one tetrahedral oxyanion nutrient ... based solely on the protonation state of the ligand. Sulfate, a conjugate base of a strong acid, is completely ionized at pH values above ...
