A phylogenetic reconstruction (cladogram) of mycoredoxins, glutaredoxins, and oxidoreductases (DsbA) points to a distinct group of mycoredoxins. The new group of mycoredoxins is shown in salmon and deep purple. To give experimental support to the phylogenetic reconstruction, biochemically characterized enzymes were utilized, such as E. coli DsbA (45), S. cerevisiae Grx (64), and H. sapiens Grx (65), among others (32).
