Table I.

Midpoint redox potentials of Trx y1 and Trx y2 determined at pH 7.9

Thioredoxin Em at pH 7.9
mV
AtTrx y1 −335
AtTrx y2 −337

The values are the average of at least 2 independent titrations, with average deviations of ±5 mV. They were independent of the total concentration of DTT and of redox equilibration time.
