Reduction of the PDI-M catalytic domains by AtNTRB as assayed using DTNB and insulin.

<p>A. DTNB reduction assay. Representative kinetic curves obtained in the presence of NADPH and AtNTRB alone or with 0.2 μM PDI-M, PDI-M(<i>a°</i>) or PDI-M(<i>a</i>). B. Insulin reduction assessed using NADPH/AtNTRB as an electron donor system and 5 μM of PDI-M, PDI-M(<i>a°</i>) or PDI-M(<i>a</i>).</p>
