t cell coopertivity

Z Krnajski, T W Gilberger, R D Walter, S Muller
The thioredoxin redox system is composed of the NADPH-dependent homodimeric flavoprotein thioredoxin reductase (TrxR) and the 12-kDa protein thioredoxin. It is responsible for the reduction of disulfide bridges in proteins such as ribonucleotide reductase and several transcription factors. Furthermore, thioredoxin is involved in the detoxification of hydrogen peroxide and protects the cell against oxidative damage. There exist two classes of TrxRs: the high M(r) and the low M(r) proteins. The well characterized Escherichia coli TrxR represents a member of the low M(r) class of proteins, whereas the mammalian, Caenorhabditis elegans, and Plasmodium falciparum proteins belong to the family of high M(r) proteins...
