NADPH-cytochrome c reductase, the flavoprotein component of the liver microsomal mixed-function oxidases, has been compared to the corresponding rat lung microsomal enzyme. Both enzymes were purified by the same methods and have identical ionic strength optima towards the reduction of cytochrome c. Antibody directed against the liver reductase identically inhibited the reduction of cytochrome c and ferricyanide by both enzymes. Double diffusion immunoprecipitation on Ouchterlony plates of deoxycholate-solubilized liver and lung microsomes resulted in converging precipitin lines indicating similar antigenic sites. The apparent molecular weights of the detergent-solubilized and bromelain-solubilized lung enzymes were determined by sodium dodecylsulfate-polyacrylamide gel electrophoresis to be 79 000 and 71 000, respectively. From the above criteria we conclude that the enzymes in these two tissues are very similar or identical proteins.
