Abstract:
We synthesized N-(4-nitrophenyl)-6-aminohexanamide (AHpNA) and used it as a substrate in a kinetic study of 6-aminohexanoate-hydrolase (NylB), a nylon oligomer-hydrolyzing enzyme. NylBs derived from Arthrobacter sp. KI72 and Pseudomonas sp. NK87 hydrolyzed AHpNA as well as a 6-aminohexanoic acid dimer, a known substrate for NylB. The K(m) values of the NylB from Arthrobacter sp. KI72 and Pseudomonas sp. NK87 for AHpNA were 0.5 mM and 2.0 mM, respectively.
