Reaction catalyzed by thioredoxin:protein disulfide reductase (1.8.4.16)

	a [protein] carrying a disulfide bond	+			=		a [protein] with reduced L-cysteine residues	+		thioredoxin-1 disulfide
	a [protein] carrying a disulfide bond	+		thioredoxin-1	=		a [protein] with reduced L-cysteine residues	+		thioredoxin-1 disulfide
