摘要: A mutant human prourokinase wherein a neutral amino acid in the epidermal growth factor (EGF) region of (human PUK) has been replaced with basic acid, or an acidic non-acidic and method for producing PUK which comprises expression by cultivating host transformed plasmid inserted DNA sequence coding said PUK. By replacing EGF is fibrinolysin half-life blood can be prolonged, affinity fibrin improved.
