Stereospecific hydroxylation of indan by Escherichia coli containing the cloned toluene dioxygenase genes from Pseudomonas putida F1.
Escherichia coli JM109(pDTG601), containing the todC1C2BA genes encoding toluene dioxygenase from Pseudomonas putida F1, oxidizes indan to (-)-(1R)-indanol (83% R) and trans-1,3-indandiol. Under similar conditions, P. putida F39/D oxidizes indan to (-)-(1R)-indanol (96% R), 1-indanone, and trans-1,3-indandiol. The differences in the enantiomeric composition of the 1-indanols formed by the two organisms are due to the presence of a 1-indanol dehydrogenase in P. putida F39/D that preferentially oxidizes (+)-(1S)-indanol.
