The ability of FNR to sense and respond to cellular O(2) levels depends on its [4Fe-4S](2+) cluster. In the presence of O(2), the [4Fe-4S](2+) cluster is converted to a [2Fe-2S](2+) cluster, which inactivates FNR as a transcriptional regulator. In this study, we demonstrate that approximately 2 Fe(2+) ions are released from the reaction of O(2) with the(More)
The oxygen sensing ability of the transcription factor FNR depends on the presence of a [4Fe-4S]2+ cluster. In the presence of O2, conversion of the [4Fe-4S]2+ cluster to a [2Fe-2S]2+ cluster inactivates FNR, but the fate of the [2Fe-2S]2+ cluster in cells grown under aerobic conditions is unknown. The present study shows that the predominant form of FNR in(More)
A large variety of techniques can be adapted for use with oxygen-sensitive samples. The growth of cells and in vivo analyses, as well as protein purification and in vitro assays, can be executed either by performing necessary steps in anaerobic environments (ranging from simple closed containers to the anaerobic chamber) or by circumventing the need for(More)
MD on Tap, a PDA application that searches and retrieves biomedical literature, is specifically designed for use by mobile healthcare professionals. With the goal of improving the usability of the application, a preliminary comparison was made of two search engines (PubMed and Essie) to determine which provided most efficient path to the desired(More)
