The introduction of disulfide bonds in proteins of the mitochondrial intermembrane space (IMS) is fundamental for their folding and assembly. This oxidative folding process depends on the disulfide donor/import receptor Mia40 and the flavin adenine d

Reversible permeable cells have been used to isolate chromatin structures during the process of chromosome condensation. Analysis of individual structures slipping out from nuclei after reversal of permeabilization revealed that chromosomes of Drosop

Heme is an essential molecule for life, as it is involved in sensing and using oxygen. Heme must be synthesized and degraded within an individual nucleated cell. Physiologic heme degradation is catalyzed by two functional isozymes of heme oxygenase,

We previously constructed computational models based on the biochemical pathway analysis of different nitric oxide (NO) synthase isoforms and found a large discrepancy between our predictions and perivascular NO measurements, suggesting the existence

Overwhelming evidence has accumulated indicating that oxidative stress is a crucial factor in the pathogenesis of neurodegenerative diseases. The major site of production of superoxide, the primary reactive oxygen species (ROS), is considered to be t

Oxygen (O(2)) sensing in blood and regulation of microvascular tone appear to involve hemoglobin (Hb) conformational changes resulting from O(2) desaturation. This observation has prompted the thought that Hb functions as both an O(2) sensor and regu

Reactive oxygen species (ROS) are often shown to damage cellular functions. The targets of oxidative damage depend on the nature of ROS produced and the site of generation. In contrast, ROS can also regulate signal transduction. In this case, ROS may
