Flavobacterium sp. KI72 metabolizes 6-aminohexanoic acid cyclic dimer, a by-product of nylon manufacture1, through two newly evolved enzymes, 6-aminohexanoic acid cyclic dimer hydrolase (EI)2 and 6-aminohexanoic acid linear oligomer hydrolase (EII)3. These enzymes are active towards man-made compounds, the cyclic dimer and linear oligomers of 6-aminohexanoic acid respectively, but not towards any of the natural amide bonds tested2,3. The structural genes of EI (nylA) and EII (nylB) are encoded… Expand
