亜硝酸レダクターゼ (NO形成)（nitrite reductase (NO-forming)）は、窒素代謝酵素の一つで、次の化学反応を触媒する酸化還元酵素である。
- 一酸化窒素 + H2O + フェリシトクロムc
亜硝酸 + フェロシトクロムc + 2 H+
反応式の通り、この酵素の基質は一酸化窒素とH2Oとフェリシトクロムc、生成物は亜硝酸とH+とフェロシトクロムcである。補因子として、FADと鉄と銅を用いる。
組織名はnitric-oxide:ferricytochrome-c oxidoreductaseで、別名にcd-cytochrome nitrite reductase; [nitrite reductase (cytochrome)] [misleading, see comments.]; cytochrome c-551:O2, NO2+ oxidoreductase; cytochrome cd; cytochrome cd1; hydroxylamine (acceptor) reductase; methyl viologen-nitrite reductase; nitrite reductase (cytochrome; NO-forming) がある。
