    1.13.11.27 | copper |
0.4 atoms of Fe per 89000 Da enzyme. Removal of copper does not correlate with loss of activity |
395367, 395377 |
| 1.13.11.27 | Iron |
0.9 atoms of Fe per 89000 Da enzyme. Removal of iron correlates with loss of activity |
395367, 395377 |
| 1.13.11.27 | Fe2+ |
restores activity after inactivation by Fe2+-chelators |
395368 |
| 1.13.11.27 | Fe2+ |
essential role for enzyme-bound Fe2+ in catalytic process |
395369 |
| 1.13.11.27 | Fe3+ |
iron in the Fe3+ form must be reduced for enzyme activity |
395369 |
| 1.13.11.27 | Iron |
0.95 mol of iron per mol of enzyme |
395369, 395375 |
| 1.13.11.27 | Iron |
0.88 mol of iron per mol of enzyme |
395370 |
| 1.13.11.27 | Iron |
iron-tyrosinate protein, high spin ferric center in a rhombic environment |
395371 |
| 1.13.11.27 | Fe2+ |
the enol tautomer of 4-hydroxyphenylpyruvate appears to form a 2:1 complex with enzyme-bound Fe2+, the tautomerizable keto group with a double bond in 3-4 position favors productive substrate binding to Fe2+ |
395375 |
| 1.13.11.27 | Zinc |
0.68 mol of zinc per mol of enzyme |
395375 |
