摘要: Novel single-chain hybrid plasminogen activators having an amino acid sequence composed of at least two subsequences corresponding in identity and number to human t-PA u-PA, mutants thereof which one the N-glycosylation sites is modified such that glycosylation cannot take place these exhibit valuable pharmacological properties. The are produced by recombinant DNA technology.
