The substrate stereospecificity of NADH-ferricyanide reductase activities in the inner mitochondrial membrane and peroxisomal membrane of potato (Solanum tuberosum L.) tubers, spinach (Spinacea oleracea L.) leaf plasma membrane, and red beetroot (Beta vulgaris L.) tonoplast were all specific for the [beta]-hydrogen of NADH, whereas the reductases in wheat root (Triticum aestivum L.) endoplasmic reticulum and potato tuber outer mitochondrial membrane were both [alpha]-hydrogen specific. In all isolated membrane fractions one or several polypeptides with an apparent size of 45 to 55 kD cross-reacted with antibodies raised against a microsomal NADH-ferricyanide reductase on western blots.
