In its reduced state this motif allows cleavage of a disulfide bond of a target protein via a bimolecular nucleophilic substitution reaction. Oxidized TRXs are reduced by TRX reductases (TRXRs). In contrast to other organisms, plants and cyanobacteria possess two independent TRXRs, a ferredoxin-...

Is evaporation a physical change? Melting, evaporation and condensation areexamples of physical change, or change of state, and are distinct from changes that cause new materials to form through a chemical reaction. ... Some curricula talk of physical changes as being reversible, and chemical chan...
Serine synthesis is crucial for tumor growth and survival, but its regulatory mechanism in cancer remains elusive. Here, using integrative metabolomics and transcriptomics analyses, we show a heterogeneity between metabolite and transcript profiles. Spec
The iron carbonyl-catalyzed reaction of diallyl ether with morpholine gives 1,4-dienylamine. Diallylamine isomerizes to 4-aza-6-methyl-1,4-nonadiene. Kiji,Jitsuo,Nishimura,... - 《Bulletin of the Chemical Society of Japan》 被引量: 0发表: 1975年 ...
