Cu(II) coordination structure in NAD glycohydrolase from Agkistrodon acutus venom studied by EPR spectroscopy
NAD glycohydrolase (NADase) from Agkistrodon acutus venom and several Cu(II) model complexes was studied by EPR spectroscopy. It was found that three nitrogen atoms may coordinate to Cu(II) ions and these nitrogen atoms might be from the imidazole groups of histidines in NADase molecule.
