Inhibition of cysteine uptake by cystinea
| Concn (μM) | [35S]cysteine uptake (%)b | |
|---|---|---|
| Cystine | Cysteine | |
| 0 | 10 | 100 |
| 1 | 10 | 60 |

Inhibition studies were performed with the CYS-1 mutant of L. pneumophila as detailed in the text. Radiolabel and l-cysteine were held constant, and the concentration of cystine was varied.
The percentages represent the means for three replicates.
