The enzymes 3-deoxy-d-manno-octulosonic acid-8-phosphate synthase (KDO8PS) and 3-deoxy-d-arabino-heptulosonic acid-7-phosphate synthase (DAHPS) catalyze analogous condensation reactions between phosphoenolpyruvate and d-arabinose 5-phosphate or d-erythrose 4-phosphate, respectively. While several similarities exist between the two enzymatic reactions, classic studies on the Escherichia coli enz...
The first structurally characterized mononuclear biscarbamate complex of Zn with eta1-coordinated carbamate ligands can be prepared by reaction between [EtZn(O2CN(iBu)2)]4 and a guanidine base. Usage of a weaker base leads to eta2-coordinated complexes.
A highly specific interaction between a metal-deficient metalloenzyme and metal ion has been utilized in the selective detection of the metal ion by surface plasmon resonance spectroscopy (SPRS). The use of SPRS and Cu-demetallated superoxide dismutase (E,Zn-SOD1) as a sensing actuator allows one to selectively and in situ detect Cu2+ without any interference that other spectroscopic methods ma...
The binding of a series of metal-binding pharmacophores (MBPs) related to the ligand 1-hydroxypyridine-2-(1H)-thione (1,2-HOPTO) in the active site of human carbonic anhydrase II (hCAII) has been investigated. The presence and/or position of a single methyl substituent drastically alters inhibitor potency and can result in coordination modes not observed in small-molecule model complexes. It is...
