288448 |
| 1.2.7.1 | Iron |
per mol, the enzyme contains 9 mol of non-heme iron, and 8 mol of acid-labile sulfur. No inhibition by sodium arsenite |
288449 |
| 1.2.7.1 | Iron |
the enzyme contains at least two [4Fe-4S] clusters. The purified and reconstituted delta subunit contains 8 Fe mol/mol |

| 1.2.7.1 | Iron-sulfur cluster |
porE encodes the 21500 Da subunit that contains a high cysteinyl residue content and a motif indicative of a [FeS] cluster. Subunit porF also also has a high cysteinyl residue content, and two [FeS] cluster motifs. Based upon these results, it is proposed that PorE and PorF are components of a specialized system required to transfer low-potential electrons for pyruvate biosynthesis |
