FIGURE 1.

Structures of the three FTR:Trx isoform complexes. All FTR molecules consisting of catalytic and variable subunit (FTRc and FTRv, respectively) are colored in light brown. (a). FTR:Trx‐y1 complex, Trx‐y1 is colored in green. (b). FTR:Trx‐y1 complex shown alongside the crystal structure of next Trx‐y1 molecule labeled Trx‐y1' and colored dark green, (c). FTR:Trx‐f2 complex, Trx‐f2 is colored in magenta, (d). FTR:Trx‐m2 complex, Trx‐m2 is colored in blue, (e). Superimposed model of Trx isoforms based on the Cα atoms of FTRc
