[[Thioredoxin]] (Trx) is an enzyme which facilitates the reduction of proteins by cysteine thiol-disulfide exchange. They contain a CXXC motif. Trx-1 is a mammalian cellular protein. Trx-2 is mitochondria-specific. In higher plants, Trx are divided to 6 groups based on their sequence. Trx M, X and Y are found in prokaryotes while F, H and O are found in eukaryotes. The images at the left and at the right correspond to one representative Trx, ''i.e.'' the crystal structure of human Thioredoxin ([[1ert]]).

Crystal Structure of Thioredoxin 1ert

Template:STRUCTURE 1ert

Thioredoxin (Trx) is an enzyme which facilitates the reduction of proteins by cysteine thiol-disulfide exchange. They contain a CXXC motif. Trx-1 is a mammalian cellular protein. Trx-2 is mitochondria-specific. In higher plants, Trx are divided to 6 groups based on their sequence. Trx M, X and Y are found in prokaryotes while F, H and O are found in eukaryotes. The images at the left and at the right correspond to one representative Trx, i.e. the crystal structure of human Thioredoxin (1ert).
