产品介绍： Thioredoxin Reductase (TR, TrxR) is the only known enzyme (EC 1.8.1.9) which is reducing thoredoxin (Trx) Involved in chloroplast protection against oxidative damage. Activity of thoredoxin is essential for growth and survival of the cell. There seem to be one isoform of NtrC protein in Arabidopsis thaliana, which includes an N-terminal reductase domain and a C-terminal domain related to thioredoxin proteins. Arabidopsis thaliana and Chlmydomonas reinhardtii NtrC proteins are ca. 568 amino acids long, but include ca. 80 amino acid signal peptides, for mature protein size of ca. 488 amino acids.
