Abstract:
:The streptokinase gene of Streptococcus equisimilis H46 was inactivated by plasmid insertion mutagenesis to study the relationship between elaboration of streptokinase and acquisition of cell-associated plasmin activity after incubation of wild-type and mutant cells in media containing plasminogen or plasmin. The results showed that H46A binds both the zymogen and active enzyme, generates surface-associated plasmin activity in the presence of plasminogen when producing streptokinase, and expresses its plasmin(ogen) receptor(s) independently of a functional streptokinase gene. At least part of the plasmin(ogen) binding capacity may be due to the glyceraldehyde-3-phosphate dehydrogenase type of receptor molecule, as judged by the detection of the corresponding gene.
