ABSTRACT:
Vectors for the expression in yeast of mammalian plasminogen derivatives such as microplasminogen and miniplasminogen are presented. Methods for expression of these proteins in a methylotrophic yeast expression system are disclosed as well as the activation and stabilisation of the recombinant proteins. The proteins of this invention are used In the treatment of focal cerebral ischemic infarction and other thrombotic diseases.
