The structural role of a sidechain to side-chain protein hydrogen bond is examined using trans-substitution of the proximal histidine of myoglobin with methylimidazoles (Barrick, Biochemistry 1994;33:6546 -6554). Modification of the chemical structure of exogenous ligands allows this hydrogen bond t
The trans-substituted histidine to glycine mutant of sperm whale myoglobin (H93G Mb) is used to study energetics of proximal hydrogen bonding, proximal ligand-heme interactions, and coupling to distal ligand binding. Comparison of mono-and dimethylimidazole structural isomers shows that the hydrogen
