CC   -!- FUNCTION: Variable subunit of the ferredoxin-thioredoxin reductase
CC       (FTR), which catalyzes the two-electron reduction of thioredoxins by
CC       the electrons provided by reduced ferredoxin.
CC   -!- SUBUNIT: Heterodimer of subunit A (variable subunit) and subunit B
CC       (catalytic subunit). Heterodimeric FTR forms a complex with ferredoxin
CC       and thioredoxin.
CC   -!- SIMILARITY: Belongs to the ferredoxin thioredoxin reductase alpha
CC       subunit family. {ECO:0000305}.
