ENZYME entry: EC 1.3.99.18

Accepted Name
Quinaldate 4-oxidoreductase.
Alternative Name(s)
Quinaldic acid 4-oxidoreductase.
Reaction catalysed
Quinaldate + acceptor + H(2)O <=> kynurenate + reduced acceptor
Comment(s)
  • 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 acid, 1,4-benzoquinone, 1,2- naphthoquinone, nitroblue tetrazolium (NBT), thionine and menadione will serve as an electron acceptor for the former enzyme and ferricyanide for the latter; Meldola blue, iodonitrotetrazolium chloride (INT), phenazine methosulfate (PMS), 2,6- dichlorophenolindophenol (DCPIP) and cytochrome c will act as electron acceptors for both.
