additional information
engineering of alpha-ketoglutaric semialdehyde dehydrogenase (KGSADH) from Azospirillum brasilense for prodduction of 3-hydroxypropanoate (HP) from 3-hydroxypropionaldehyde (3-HPA). A directed evolutionary strategy is adopted as the engineering approach for modifying the substrate-binding sites of KGSADH. The residues in the binding sites for the substrates, 3-HPA and NAD+, are randomized, and the resulting libraries are screened for higher activity. Isolated KGSADH variants have significantly lower Km values for both the substrates. The enzymes also show higher substrate specificities for aldehyde and NAD+, less inhibition by NADH, and greater resistance to inactivation by 3-HPA than the wild-type enzyme. A recombinant Pseudomonas denitrificans strain expressing one of the engineered KGSADH variants exhibits less accumulation of 3-HPA, decreased levels of inactivation of the enzymes, and higher cell growth than that expressing the wild-type KGSADH. The flask culture of the Pseudomonas denitrificans strain with the mutant KGSADH results in about 40% increase of 3-HP titer (53 mM) compared with that using the wild-type enzyme (37 mM).
