Journal ArticleDOI
Reconstitution and characterization of the polynuclear iron-sulfur cluster in pyruvate formate-lyase-activating enzyme. Molecular properties of the holoenzyme form.
TL;DR: The iron-sulfur cluster complement proved to be a prerequisite for effective binding of adenosylmethionine, which induces a characteristic shift of the EPR signal shape of the reduced enzyme form ([4Fe-4S]+) from axial to rhombic symmetry.
Journal ArticleDOI
Flavonol 2,4-dioxygenase from Aspergillus niger DSM 821, a type 2 CuII-containing glycoprotein.
Hilda-Katharina Hund,Jörn Breuer,Franz Lingens,Jürgen Hüttermann,Reinhard Kappl,Susanne Fetzner +5 more
TL;DR: The EPR spectrum of flavonol 2,4-dioxygenase (as isolated) showed the characteristic parameters of a nonblue type 2 CuII protein, and metal chelating agents strongly inhibited the enzymatic activity, but inactivation was not accompanied by loss of copper.
Journal ArticleDOI
The active site of purple acid phosphatase from sweet potatoes (Ipomoea batatas) metal content and spectroscopic characterization.
Atila Durmus,Christoph Eicken,Bernd Horst Sift,Andreas Kratel,Reinhard Kappl,Jürgen Hüttermann,Bernt Krebs +6 more
TL;DR: It is shown that spPAP contains a Fe(III)-Zn(II) center in the active site as previously determined for the purple acid phosphatase from red kidney bean (kbPAP), and an alignment of the amino acid sequences suggests that the residues involved in metal-binding are identical in both plant PAPs.
Journal ArticleDOI
Specific formation of electron gain and loss centres in X-irradiated oriented fibres of DNA at low temperatures
TL;DR: Electron spin resonance (e.s.r.) spectra have been measured from six different DNA specimens prepared as oriented A-DNA fibres after irradiation and identified two primary species stabilized at low temperatures in thymine-containing DNA which are assigned to the cation of guanine and the anion of thymine.
