  • PubMed Abstract: 

    Thioredoxins are ubiquitous proteins that serve as reducing agents and general protein disulfide reductases. The structures of thioredoxins from a number of species, including man and Escherichia coli, are known. Cyanobacteria, such as Anabaena, contain two thioredoxins that exhibit very different activities with target enzymes and share little sequence similarity. Thioredoxin-2 (Trx-2) from Anabaena resembles chloroplast type-f thioredoxin in its activities and the two proteins may be evolutionarily related. We have undertaken structural studies of Trx-2 in order to gain insights into the structure/function relationships of thioredoxins.
