Influence of the multicopper oxidase inhibitor TTM on Fe uptake
| Treatment | Nutritional Status
|
|
|---|---|---|
| +Fe | −Fe | |
| Control | 5.66 (100) | 27.23 (100) |
| 25 μm TTM, 0.5 h | 5.99 (106) | 21.53 (79) |
| 25 μm TTM, 4 h | 4.68 (83) | 22.51 (83) |
| 250 μm TTM, 0.5 h | 1.63 (29) | 10.68 (39) |
| 250 μm TTM, 4 h | 1.47 (26) | 2.88 (11) |
Twenty-five and 250 μm TTM were added to a culture containing 4.4 × 108 cells mL−1. TTM was incubated for 0.5 and 4 h and the Fe uptake was measured (pmol 106 cells−1 h−1). These results are averages of two independent assays. Percent inhibition is shown in parentheses.
