To reduce other proteins, first happens an attack from Cys32, creating an intermolecular dissulfide bond, represented <scene name='91/911850/C32_s-s_c206/1'>here</scene> between residue Cys32 from Trx1 and residue Cys206 from '''[[MsrA]]'''. After it, residue Cys35 attacks Cys32, creating a dissulfide bond between the two cysteines in Trx1's catalytic site.
