The NMR titration curves of proton chemical shifts were observed for the C2 protons of histidine residues in intact bovine pancreatic RNAase A (EC 3.1.27.5) and carboxyalkylated RNAase A. By comparing...
The dynamics of the complex formation between pyridoxal 5'-phosphate (PLP) and histidine in the presence of bacterial histidine decarboxylase was examined. Since PLP is able to form a cyclic product w...
Inactivation of Cu,Zn-superoxide dismutase (Cu,Zn-SOD) by its own reaction product H2O2 is a well-known phenomenon. Generation of the hydroxyl radical has been a matter of great concern, and the targe...
Histone H4 is a good substrate in vitro for the protein histidine kinase activity found both in Physarum polycephalum nuclear extracts and in Saccharomyces cerevisiae cell extracts. However, histone H...
The aromatic region of the proton NMR spectrum of human adult hemoglobin (HbA) contains resonances from at least 11 titratable histidine residues. Assignments for five beta chain histidines have previ...
Density functional theory calculations have been used to evaluate the effects of inter-ring interactions within a covalently linked histidine-tyrosine cofactor such as that which is a ligand to the Cu...
