abstract::Nitrite represents a bioactive reservoir of nitric oxide (NO) that may modulate vasodilation, respiration and cytoprotection after ischemia-reperfusion injury. Although nitrite formation is thought to occur via reaction of NO with oxygen, this third-order reaction cannot compete kinetically with the reaction of NO wit...

abstract::Small-molecule inhibitors of kinesin-5 (refs. 1-3), a protein essential for eukaryotic cell division, represent alternatives to antimitotic agents that target tubulin. While tubulin is needed for multiple intracellular processes, the known functions of kinesin-5 are limited to dividing cells, making it likely that kin...

abstract::Mammals that degrade uric acid are not affected by gout or urate kidney stones. It is not fully understood how they convert uric acid into the much more soluble allantoin. Until recently, it had long been thought that urate oxidase was the only enzyme responsible for this conversion. However, detailed studies of the m...

The structure of actin filament changes spontaneously and can also be regulated by actin-binding proteins, allowing actin to readily function in response to external stimuli.
