1. A polypeptide comprising:
- (a) a single N-terminal kringle domain wherein the last four amino acid residues within the single N-terminal kringle domain are identical to residues at positions 91-94 of SEQ ID NO;
2; and
(b) a C-terminal domain activation site and serine protease domain;
wherein the polypeptide binds to immobilized lysine; and
wherein the polypeptide is at least 95% identical to the sequence shown in SEQ ID NO;

Abstract
Polynucleotides and polypeptides relating to a recombinantly modified plasmin(ogen) molecule are provided. The plasmin(ogen) molecule has a single kringle domain N-terminal to the activation site present in the native human plasminogen molecule, combined such that no foreign sequences are present, and exhibits lysine-binding and significant enzymatic characteristics associated with the native enzyme.
