1.1.1.1 expression of wild-type and mutant enzymes in Escherichia coli Pyrococcus furiosus

Protein Variants

EC Number Protein Variants Comment Organism
1.1.1.1 H255R the H255R single mutant exhibits an increased binding affinity toward NADP+ and a concomitant reduction in affinity for NAD+. The apparent kcat for H255R is about 60% of that of the wild-type with NAD+, but it is sixfold higher than the wild-type with NADP+. Position 255 is important for recognizing NADP(H), but is not the sole determinant of cofactor specificity Pyrococcus furiosus
1.1.1.1 K249G catalytic efficiency increases 5fold for NADH, the efficiency with NADPH increases more than 30fold in comparison to the wild-type Pyrococcus furiosus
1.1.1.1 K249G/H255R the catalytic efficiency with NADH increases 4fold, the efficiency with NADPH increases more than 16fold. In the oxidation reaction, the kcat with NAD+ improves by 15fold for the double mutant over the wild type enzyme. With NADP+ the kcat is nearly two orders of magnitude larger than the wild-type. Mutant exhibits significantly improved activity and broadened cofactor specificity as compared to the wild-type enzyme Pyrococcus furiosus
