Purification and characterization of cellobiose dehydrogenase, a novel extracellular hemoflavoenzyme from the white-rot fungus Phanerochaete chrysosporium.

abstract：:Application of nanosecond pulsed electric fields (nsPEFs) has attracted attention as a unique tool in life sciences, especially for cancer therapy, but the molecular mechanism of its action on living organisms is yet to be fully elucidated. Here, we report a transient activation of signaling pathways involving mitogen...
