1.6.5.10 | 1,4-benzoquinone + NADPH + H+ |
1,4-benzoquinone is oxidized almost stoichiometric amount of NADPH, suggesting that it is reduced to its hydroquinone with a two-electron reduction mechanism |

1.6.5.10 | 1,4-naphthoquinone + NADPH + H+ |
1,4-naphthoquinone participates in the redox cycling in their reduction by this enzyme as evidenced by excess NADPH oxidation over quinone reduction. CBR4 may reduce 1,4-naphthoquinone in the two-electron reduction mechanism, but produces reactive superoxide and semiquinones through their redox cycling |
