1985 Cell Structure and Function  
Twelve amino acid sequences of kringle-forming polypeptides were compiled from the known sequences of urokinase A-chain (human), a tissue-type plasminogen activator (human), prothrombin (human and bovine), and plasminogen (human). Their sequence homologies with maximum match were examined by a computer program. A homology alignment and graphic matrix analyses did show that they had a great degree of homology. All the cystein residues responsible for the kringle structures of urokinase and the
