| 1.11.1.18 | Vanadium |
presence of vanadium coordinated to oxygen/nitrogen either as vanadium(V) (in the native, native plus bromide, and native plus peroxide samples) or vanadium(IV) (in the reduced enzyme). There are structural changes at the metal site on reduction of the native enzyme, notably a lengthening of the average inner-shell distance and the presence of terminal oxygen together with histidine and oxygen-donating residues |

| 1.11.1.18 | Vanadium |
contains 0.3 vanadium ions per subunit |

| 1.11.1.18 | Vanadium |
contains 0.38 vanadium ions per subunit |

| 1.11.1.18 | Ca2+ |
contains one calcium atom per subunit |

| 1.11.1.18 | Vanadium |
requires vanadium for enzyme activity. The enzyme activity increases ca. 250% with the action of V5+ on the isolated enzyme, since more than 2/3 of the protein molecules are in the apo form. This effect of V5+ addition is inhibited in phosphate buffer, probably because phosphate and vanadate compete for the active site |

| 1.11.1.18 | Vanadium |
the substrate bromide does not bind to active site vanadium but to a light atom, possibly carbon, in its vicinity |
