title: 6-Aminohexanoate oligomer hydrolases from the alkalophilic bacteria Agromyces sp. strain KY5R and Kocuria sp. strain KY2.
abstract: Alkalophilic, nylon oligomer-degrading strains, Agromyces sp. and Kocuria sp., were isolated from the wastewater of a nylon-6 factory and from activated sludge from a sewage disposal plant. The 6-aminohexanoate oligomer hydrolases (NylC) from the alkalophilic strains had 95.8 to 98.6% similarity to the enzyme in neutrophilic Arthrobacter sp. but had superior thermostability, activity under alkaline conditions, and affinity for nylon-related substrates, which would be advantageous for biotechnological applications.
