Purification and Properties of Diphosphopyridine Nucleotide Diaphorase of Human Erythrocytes

Abstract

Hereditary methemoglobinemiaof the enzymatic type (I) has been shown to be due to the absence of reduced diphosphopyridine nucleotide diaphorase activity in red cells (2).The present communication describes the properties of this enzyme as prepared from normal human red cells.METHODS
