Uclacyanins, stellacyanins, and plantacyanins are distinct subfamilies of phytocyanins: plant-specific mononuclear blue copper proteins.
The cDNAs encoding plantacyanin from spinach were isolated and characterized. In addition, four new cDNA sequences from Arabidopsis ESTs were identified that encode polypeptides resemblingExpand

Enhanced electron transfer and lauric acid hydroxylation by site-directed mutagenesis of CYP119.
CYP119, a cytochrome P450 from a thermophilic organism for which a crystal structure is available, is shown here to hydroxylate lauric acid in a reaction supported by putidaredoxin and putidaredoxinExpand

DNA-PEG-DNA triblock macromolecules for reagentless DNA detection.
The sandwich assay is the most common design for electrochemical DNA sensors. This assay consists of three individual DNA components: an immobilized capture strand, a target strand, and a probeExpand

Electrocatalytic reductions of nitrite, nitric oxide, and nitrous oxide by thermophilic cytochrome P450 CYP119 in film-modified electrodes and an analytical comparison of its catalytic activities
Previous investigations of nitrite and nitric oxide reduction by myoglobin in surfactant film modified electrodes characterized several distinct steps in the denitrification pathway, includingExpand

A novel heme and peroxide-dependent tryptophan-tyrosine cross-link in a mutant of cytochrome c peroxidase.
The crystal structure of a cytochrome c peroxidase mutant where the distal catalytic His52 is converted to Tyr reveals that the tyrosine side-chain forms a covalent bond with the indole ring nitrogenExpand

Conformationally Gated Electrochemical Gene Detection
The synthesis and characterization of a 26‐base DNA hairpin containing both a redox‐active reporter (ferrocene) and terminal thiol functionality for electrochemical gene detection is described. ThisExpand

Dendritic molecular capsules for hydrophobic compounds.
Reichardt's dye, a highly solvatochromic dye, was encapsulated within poly (glycerol succinic acid) ([Gn]-PGLSA-OH) dendrimers to investigate the interior environment of these dendriticExpand

Efficient trapping of HNO by deoxymyoglobin.
Nitrosyl hydride, HNO, also commonly termed nitroxyl, is a transient species that has been implicated in the biological activity of nitric oxide, NO. Herein, we report the first generation of aExpand

Bonding in HNO-myoglobin as characterized by X-ray absorption and resonance raman spectroscopies.
The EXAFS and resonance Raman spectra on the HNO-myoglobin adduct, 1, are consistent with the presence of HNO bound to a heme center. The three-dimensional structure about the heme center of 1Expand

Electrochemistry of the CuA domain of Thermus thermophilus cytochrome ba3
Abstract The electrochemistry of a water-soluble fragment from the CuA domain of Thermus thermophilus cytochrome ba3 has been investigated. At 25  °C, CuA exhibits a reversible reduction at aExpand
