Lactoperoxidase-catalyzed iodination of cell cultures infected with mycoplasma.
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.
