enzyme shows a copper-to-protein ratio of 1.08
-
1.2 mol per mol protein
-
1 atom of Cu per molecule of enzyme
-
contains 0.048 mol of Cu per mol of enzyme
-
copper content is 0.12 atoms per monomer
-
the enzyme expresses the soluble enzyme form under copper limitation, and the membrane-bound particulate MMO at high copper-to-biomass ratio, mechanism of the copper switch involves a tetrameric 480 kDA sensor protein MmoS, encoded by gene mmoS, as part of a two-component signaling system, domain organization, MmoS contains a FAD cofactor, indirect regulation without binding of copper to MmoS, overview
-
0.03 atoms per 42000 g/mol peptide
-
both small contents of Fe and Cu in the plants lead to an overexpression of the gene encoding the enzyme and enhanced FC-R activity in the plants
-
contains one copper atom per molecule
-
protein contains a radical-coupled copper complex, a mononuclear Cu(II) center with an axial coordination
-
protein contains a copper-center
-
6 copper atoms per molecule
-
two copper atoms, CuA and CuB, are located in the active site and each is coordinated by three histidine residues. CuA is coordinated by His87, His108, and His117 residues, while CuB is coordinated by His241, His245 and His275
-
2 mol copper /mol FAD, cupric ion can be removed by dialysis against cyanide, copper is not involved in redox reaction
-
metal content: 0.1 mol per mol of enzyme
-
contains 1 mol of copper per subunit
-
might be a copper metalloenzyme
-
study on reaction of copper(II)-nitrito complexes with tridentate and tetradentate, with either O,O'-bidentate or O-unidentate modes of nitrite binding to the cupric center . Differing modes of nitrite coordination to the copper(II) ion lead to differing kinetic behavior
-
2.9 atoms per subunit
-
the enzyme contains a CuA center in its small subunit
-
the heterobimetallic active-site heme 2 has a Cu(I) ion juxtaposed to a heme c at a Fe-Cu distance of 4.4 A. While the combination of metals is reminiscent of respiratory heme–copper oxidases, the oxidation-labile Cu(I) centre of MccA does not seem to undergo a redox transition during catalysis. The copper-depleted form II of MccA, the absence of the heterometal allows for a binding mode of sulfite that is similar to the one seen in the siroheme-containing enzymes or in NrfA. In the structure of the Cu-containing, high-activity form I of MccA, all 12 monomers in the asymmetric unit have a ligand bound to heme 2
-
Co(II) and Cu(II) can be reconstituted into the protein with similar stoichiometry
-
1:1 stoichiometry with Co
-
high affinity copper-binding protein
