   1.2.7.B2 | Tungsten |
the enzyme from Pyrococcus furiosus uses exclusively tungsten to synthesize the catalytically active forms of formaldehyde ferredoxin oxidoreductase and active molybdenum- or vanadium-containing isoenzymes are not expressed when the cells are grown in the presence of these other metals |
722490 |
| 1.2.7.B2 | Tungsten |
the tungsten in the active enzyme is a two-electron acceptor, W(VI/IV) |
674933 |
| 1.2.7.B2 | Tungsten |
tungsten-containing enzyme. The enzyme contains 3.3 gatom of tungsten per 280000 Da g of enzyme |
644682 |
| 1.2.7.B2 | Tungsten |
tungsten-containing enzyme. The enzyme contains approximately 1 W atom, 4 Fe atoms, and 1 Ca atom per subunit |
644689 |
| 1.2.7.B2 | Tungsten |
tungsten-containing protein |
723098 |
| 1.2.7.B2 | Tungsten |
tungsten-dependent enzyme, no activity when tungsten is replaced by molybdenum |
722823 |
| 1.2.7.B2 | Tungsten |
tungsten-dependent enzyme. A mechanism is proposed in which the formaldehyde substrate binds directly to the tungsten ion. W(VI)=O then performs a nucleophilic attack on the formaldehyde carbon to form a tetrahedral intermediate. In the second step, which is calculated to be rate limiting, a proton is transferred to the second-shell Glu308 residue, coupled with a two-electron reduction of the tungsten ion |
