Structural implications derived from the analysis of electron paramagnetic resonance spectra of natural and artificial copper proteins
Abstract
An extension of a method relating chemical structure to the EPR parameters A∥ and g∥ is presented. For complexes having the same atoms of ligation, a decrease in charge of the metal-ligand complex decreases g∥ and increases A∥. From this analysis, one concludes that in artificial copper proteins as well as in the naturally occurring nonblue copper proteins copper is ligated to oxygen and nitrogen but not to sulfur. A method is presented for the interpretation of EPR changes that occur with ligand exchange reactions at the Type 2 (nonblue) copper sites such as occur in laccase.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
