EC 1.3.99.18 is Orphan !
Common name :Quinaldate 4-oxidoreductase

Systematic name :Quinoline-2-carboxylate:acceptor 4-oxidoreductase (hydroxylating)

Other names :Quinaldic acid 4-oxidoreductase
Comments :The enzyme from Pseudomonas sp. AK2 also acts on quinoline-8-carboxylate, whereas that from Serratia marcescens 2CC-1 will oxidize nicotinate; quinaldate is a substrate for both of these enzymes. 2,4,6-trinitrobenzene sulfonate, 1,4-benzoquinone, 1,2-naphthoquinone, nitroblue tetrazolium, thionine and menadione will serve as an electron acceptor for the former enzyme and ferricyanide for the latter; Meldola blue, iodonitrotetrazolium chloride, phenazine methosulfate, 2,6-dichlorophenolindophenol and cytochrome c will act as electron acceptors for both.
