Resolving ligand hyperfine couplings of type 1 and 2 Cu(II) in ascorbate oxidase by high field pulse EPR correlation spectroscopy.
نویسندگان
چکیده
Ascorbate oxidase contains two paramagnetic Cu(ii) binding sites, type 1 (T1) and type 2 (T2) and in both sites the Cu(ii) is coordinated to histidine residues. We use several pulse EPR techniques at high field (95 GHz) to determine ligand (1)H and (14)N hyperfine couplings in the two sites and identify the T1 signals by a new triple resonance correlation technique named THYCOS.

Influence of counterions on the structure of bis(oxazoline)copper(II) complexes; an EPR and ENDOR investigation.
X- and Q-band EPR and ENDOR spectroscopy was used to study the structure of a series of heteroleptic and homoleptic copper bis(oxazoline) complexes, based on the (-)-2,2'-isopropylidenebis[(4S)-4-phenyl-2-oxazoline] ligand and bearing different counterions (chloride versus triflate); labelled [Cu(II)(1a-c)]. The geometry of the two heteroleptic complexes, [Cu(II)(1a)] and [Cu(II)(1c)], depended...
متن کاملPulsed EPR/ENDOR characterization of perturbations of the Cu(A) center ground state by axial methionine ligand mutations.
The effect of axial ligand mutation on the Cu(A) site in the recombinant water soluble fragment of subunit II of Thermus thermophilus cytochrome c oxidase ba(3) has been investigated. The weak methionine ligand was replaced by glutamate and glutamine which are stronger ligands. Two constructs, M160T0 and M160T9, that differ in the length of the peptide were prepared. M160T0 is the original solu...
متن کاملAzide binding to the trinuclear copper center in laccase and ascorbate oxidase.
Azide binding to the blue copper oxidases laccase and ascorbate oxidase (AO) was investigated by electron paramagnetic resonance (EPR) and pulsed electron-nuclear double resonance (ENDOR) spectroscopies. As the laccase : azide molar ratio decreases from 1:1 to 1:7, the intensity of the type 2 (T2) Cu(II) EPR signal decreases and a signal at g approximately 1.9 appears. Temperature and microwave...
متن کاملSpin delocalization over type zero copper.
Hard-ligand, high-potential copper sites have been characterized in double mutants of Pseudomonas aeruginosa azurin (C112D/M121X (X = L, F, I)). These sites feature a small A(zz)(Cu) splitting in the EPR spectrum together with enhanced electron transfer activity. Due to these unique properties, these constructs have been called "type zero" copper sites. In contrast, the single mutant, C112D, ...
متن کاملAn ENDOR and DFT analysis of hindered methyl group rotations in frozen solutions of bis(acetylacetonato)-copper(II).
ENDOR spectroscopy and DFT calculations have been used to thoroughly investigate the ligand hyperfine couplings for the bis(acetylacetonato)-copper(ii) complex [Cu(acac)2] in frozen solution. Solutions of [Cu(acac)2] were prepared under anhydrous conditions, and EPR revealed that the g and (Cu)A values were affected by traces of water present in the solvent. The ligand (H)Ai hyperfine couplings...
