Magnitude and Origin of the Enhanced Basicity of the Catalytic Glutamate of Triosephosphate Isomerase
Glu-167 of triosephosphate isomerase from Trypanosoma brucei brucei (TbbTIM) acts as the base to deprotonate substrate to form an enediolate phosphate trianion intermediate. We report that there is a large ~6 pK unit increase in the basicity of the carboxylate side chain of Glu-167 upon binding of t...
