additional information | invertion of the cofactor specificity of the NADP+-dependent enzyme glyoxylate reductase by a structure-guided, semirational strategy, overview. The heuristic-based approach leverages the diversity and sensitivity of catalytically productive cofactor binding geometries to limit the problem to an experimentally tractable scale. Experimental validation of the CSR-SALAD method for switching cofactor preference to NAD while retaining catalytic activity | Arabidopsis thaliana |
R31L/T32K/K35D/C68R | site-directed mutagenesis of Rosmann fold (c.2.1.6) residues leading to a switch of cofactor preference of the enzyme from NADP(H) to NAD(H), altered cofactor kinetics of the mutant enzyme R31L/T32K/ K35D/C68R compared to the wild-type, overview | Arabidopsis thaliana |
