Nitrofuran-Reducing Enzymes of Euglena

Nitrofuran-Reducing Enzymes of Euglena

SYNOPSIS. Euglena gracilis strain Z, green, dark‐grown, and “bleached”with N‐methyl‐N‐nitro‐N‐nitrosoguanidine, was found to contain 2 soluble enzymes which reduce nitrofurans. A small amount of activity was demonstrated also in a particulate fraction of sonic extracts, but none in isolated chloropl...

Zusammenfassung:SYNOPSIS. Euglena gracilis strain Z, green, dark‐grown, and “bleached”with N‐methyl‐N‐nitro‐N‐nitrosoguanidine, was found to contain 2 soluble enzymes which reduce nitrofurans. A small amount of activity was demonstrated also in a particulate fraction of sonic extracts, but none in isolated chloroplasts. The reduction of 5 nitrofurans, having widely differing bleaching activities, by each of the 2 enzymes was examined.
