L45 (≠ R45) mutation to R: Shows a marked increase in the catalytic efficiency with NADP(+).
LS 45:46 (≠ RN 45:46) mutation to RD: Does not impair the catalytic activity with NAD(+). Slightly increases the activity, but slightly decreases the affinity for NADP(+).; mutation to RR: Causes a shift in coenzyme preference from NAD(+) to NADP(+) by a factor of 974. Shows a slight decrease in the catalytic efficiency with NAD(+) and a 4.5-fold increase in catalytic efficiency with NADP(+).
