title: Immunoferrin labeling of respiratory nitrate reductase in membrane vesicles of Bacillus licheniformis and Klebsiella aerogenes.
abstract: The indirect immunoferritin labeling method was used to localize the membrane-bound respiratory nitrate reductase in membrane vesicles and protoplasts or sphereplasts of Bacillus licheniformis and Klebsiella aerogenes, respectively. For a comparison of the labeling of the various vesicle preparations, which differed not only in size but also in the percentage of inside-out orientation, a quantification of the results was needed to circumvent the problem of non-specifically bound ferritin. From the results of sidedness of the nitrate reductase in the cytoplasmic membrane of the above-mentioned bacteria was determined as being cytoplasmic in B. licheniformis and as transmembranous in K. aerogenes.
