medicine | triple mutant L86F/L219F/P456A or a double mutant L86F/L219F enzyme will serve as a good model of mosquito CYPOR in future structural studies and in the development of new antimalarial agents | Anopheles minimus |
Cloned (Comment) | Organism |
---|---|
NADPH-cytochrome c oxidoreductase lacking the first 55 amino acid residues (DELTA55AnCY) is expressed in Escherichia coli loses FMN, leading to an unstable protein and subsequent aggregation. The triple mutant L86F/L219F/P456FDELTA55AnCY exhibits increased stability with significant reduction in aggregation compared to the wild-type enzyme | Anopheles minimus |
Protein Variants | Comment | Organism |
---|---|---|
L219F | mutant enzyme contains 0.83 FMN and 0.5 FAD compared to 0.53 FMN and 1.05 FAD for wild-type enzyme | Anopheles minimus |
L86F | mutant enzyme contains 0.83 FMN and 0.5 FAD compared to 0.92 FMN and 1.05 FAD for wild-type enzyme | Anopheles minimus |
L86F/L219F/P456A | increased stability with significant reduction in aggregation compared to the wild-type enzyme. The triple mutant is purified in high yield with stoichiometries of 0.97 FMN and 0.55 FAD (compared to 0.92 FMN and 1.05 FAD for wild-type enzyme). Deficiency in FAD content is overcome by addition of exogenous FAD to the enzyme. Both wild-type and the triple mutant follow a two-site ping-pong mechanism with similar kinetic constants | Anopheles minimus |
P456A | mutant enzyme contains 0.28 FMN and 0.5 FAD compared to 0.5 FMN and 1.05 FAD for wild-type enzyme | Anopheles minimus |
