Investigating the Tyrosine-Histidine Linkage in the Copper B Site of Cytochrome C Oxidase: Model Studies Utilizing a Zinc Imidazole-Phenol Containing Complex
… imidazole-phenol moiety. The resultant Zn(II) complex, [Zn(BPAIP)(Br)]+, was found to exhibit a decreased pK A (8.24) and increased oxidation potential relative to the unbound BPAIP. In addition, the stability of [Zn(BPAIP)(Br)]+ in buffered D2O was found to be pH dependent. The …
