NADPH-specific quinone reductase is induced by 2-methylene-4-butyrolactone in Escherichia coli

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1996
2-Methylene-4-butyrolactone (MBL), an inducer of NAD(P)H:(quinone acceptor) oxidoreductase (EC 1.699.2) in animal cells, was found to induce NADPH-specific quinone reductase about 25-fold in Escherichia coli. MBL induced NADPH-quinone reductases with relative mobilities (Rm) of 0.70, 0.76 and 0.91 on polyacrylamide gel electrophoresis (PAGE).
