Fig. 4From: Identification, characterization of two NADPH-dependent erythrose reductases in the yeast Yarrowia lipolytica and improvement of erythritol productivity using metabolic engineeringEffect of pH on the specific activity of ER10 and ER25 reductases. Purified enzymes were mixed with Mcilvaine’s buffer and assayed at various pH values ranging from 3.0 to 8.0. The values provided are the means of three independent replicates; the standard deviations represented less than 10% of the meansBack to article page
