EC 1.6.3.5

Accepted name: renalase

Reaction: (1) 1,2-dihydro-β-NAD(P) + H+ + O2 = β-NAD(P)+ + H2O2
(2) 1,6-dihydro-β-NAD(P) + H+ + O2 = β-NAD(P)+ + H2O2

Other name(s): αNAD(P)H oxidase/anomerase (incorrect); NAD(P)H:oxygen oxidoreductase (H2O2-forming, epimerising) (incorrect)

Systematic name: dihydro-NAD(P):oxygen oxidoreductase (H2O2-forming)

Comments: Requires FAD. Renalase, previously thought to be a hormone, is a flavoprotein secreted into the blood by the kidney that oxidizes the 1,2-dihydro- and 1,6-dihydro- isomeric forms of β-NAD(P)H back to β-NAD(P)+. These isomeric forms, generated by nonspecific reduction of β-NAD(P)+ or by tautomerization of β-NAD(P)H, are potent inhibitors of primary metabolism dehydrogenases and pose a threat to normal respiration.
