WebNov 12, 2024 · The enzyme (from A. niger) exhibits a KM of about 10 μM for its substrate NADP +. A maximal absorbance difference at 340 nm ( ε = 6220 M −1 cm −1) of 0.06 is obtained when all of 10 μM NADP + is converted to NADPH. If only 10% substrate conversion is permissible, this value can be 0.006.
