title: Lactoperoxidase-catalyzed iodination of cell cultures infected with mycoplasma.
abstract: Hamster BHK cells or secondary cultures of mouse embryo fibroblasts are not iodinated by lactoperoxidase in the absence of hydrogen peroxide. When such cell cultures are infected with a noncultivable strain of M. hyorhinis, endogenous peroxide generation is sufficient to permit nearly maximal iodination. The SDS-polyacrylamide gel pattern of iodinated cell surface polypeptides is essentially the same regardless of the source of peroxide and whether or not the cultures are infected with mycoplasma.
