Abstract Glycerol dehydratase was the critical enzyme in the metabolic pathway of converting glycerol to 3-hydroxypropionic acid. It was subjected to suicide inactivation by the natural substrate glycerol during catalysis. The inactivated glycerol dehydratase will influence the production of 3-hydroxypropionic acid. Therefore, the dhaB gene encoding glycerol dehydratase and gdrA, gdrB gene encoding glycerol dehydratase-reactivating factor from Klebsiella pneumoniae, the aldH gene encoding aldehyde dehydrogenase from Saccharomyces cerevisiae W303 were amplified by PCR. dhaB, gdrA, gdrB and aldH gene was employed to construct the recombinant strain Escherichia coli JM109/pEtac-dhaB-tac-aldH and E. coli JM109/pEtac-dhaB-gdrAB-tac-aldH. The effects of gdrA, gdrB expression on 3-hydroxypropionic acid production from glycerol were investigated. When cultivated aerobically on medium, the recombinant E. coli JM109/pEtac-dhaB-gdrAB-tac-aldH and E. coli JM109/pEtac-dhaB-tac-aldH produced 3-HP at a maximum of 4.0 g/L and 0.54 g/L. The results showed that the gdrA, gdrB expression could reactivated the activity of the inactivated glycerol dehydratase. Compare with E. coli JM109/pEtac-dhaB-tac-aldH, E. coli cells coexpressing both gdrA and gdrB with the glycerol dehydratase genes showed that the production of 3-HP was increased by 6.4fold.
