... and finally reduction of nitrous oxide to nitrogen. In the denitrification path- way, nitrite reduction is the key step, as it is the point of divergence from assimilatory nitrogen metabolism in which ... pantotrophus catalyses the one electron reduction of nitrite to nitric oxide using two heme cofactors. The site of nitrite reduction is the d 1 heme, which is synthesized...

Although there have been reports that there is protease contamination of some commercially available bacitracin preparations [31], we were loathe to fractionate the material to ensure that there ... aggregation and the chaperone activity of BiP In addition to disulfide bond formation, PDI has been shown to have chaperone-like activity [34]. As rhoda- nese contains no disulfide bonds, and...

... depo- larization. On the basis of experimental and theoretical considerations, we now consider how Ca 2+ oscillations can be synchronized across multiple cells in a syn- cytium. Synchronization of ... mechanism is a coupled oscillator -based synchronization of Ca 2+ oscillations across cells that drives membrane potential changes and causes coordinated contractions. The key elements...

All results indicate a potential function of KLF4 in the pathogenesis of atherosclerosis through the regulation effect on ... signalling, implicating KLF4 as a regulator of key signalling pathways that control macrophage activation [3]. Furthermore, it has also been demonstrated that KLF4 is required for...

Recently, it was shown that a group of isolates of the ... involved in the catalytic activity of both enzymes. The overall results indicated that BHs have new substrate specificities with a new catalytic activity that can be designated...

The NMR data strongly support the hypo- thesis ... if the reaction occurs in D 2 O [16]. Another possibility is that deprotonation and reprotonation occur without the proton exchanging with bulk water. However, de- protonatio...
