Accepted name: isoquinoline 1-oxidoreductase
Reaction: isoquinoline + acceptor + H2O = isoquinolin-1(2H)-one + reduced acceptor
Systematic name: isoquinoline:acceptor 1-oxidoreductase (hydroxylating)
Comments: The enzyme from Pseudomonas diminuta is specific towards N-containing N-heterocyclic substrates, including isoquinoline, isoquinolin-5-ol, phthalazine and quinazoline. Electron acceptors include 1,2-benzoquinone, cytochrome c, ferricyanide, iodonitrotetrazolium chloride, nitroblue tetrazolium, Meldola blue and phenazine methosulfate.
