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.
含有编码来自恶臭假单胞菌F1甲苯双加氧酶的todC1C2BA基因的大肠杆菌JM109(pDTG601),将茚满氧化为(-)-(1R)-茚醇(83% R)和顺式-1,3-茚二醇。在相似条件下,恶臭假单胞菌F39/D将茚满氧化为(-)-(1R)-茚醇(96% R)、1-茚酮和顺式-1,3-茚二醇。两种微生物形成的1-茚醇对映体组成的差异是由于恶臭假单胞菌F39/D中存在优先氧化(+)-(1S)-茚醇的1-茚醇脱氢酶。
