The occupancy of two distinct conformations by active‐site histidine‐119 in crystals of ribonuclease is modulated by pH

et al. 1994

Structures of a semisynthetic RNase have been obtained to a resolution of 2.0 A at pH values of 5.2, 6.5, 7.5, and 8.8, respectively. The principle structural transformation occurring over this pH range is the conversion of the side chain of active site residue His-119 from one conformation (chi 1 = -43 degrees to -57 degrees) at low pH to another (chi 1 = +159 degrees to +168 degrees) at higher pH values. On the basis of this observation, a model is proposed that reconciles the disparate pK values for His-119 in the enzyme-substrate complex that have been deduced from kinetic studies and from proton NMR measurements in the presence of pseudosubstrates.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
