Reaction: quinoline + acceptor + H2O = quinolin-2(1H)-one + reduced acceptor
Systematic name: quinoline:acceptor 2-oxidoreductase (hydroxylating)
Comments: Quinolin-2-ol, quinolin-7-ol, quinolin-8-ol, 3-, 4- and 8-methylquinolines and 8-chloroquinoline are substrates. Iodonitrotetrazolium chloride can act as an electron acceptor.
