title: Structure of the carboxyl-terminal half of human alpha 2-plasmin inhibitor deduced from that of cDNA.
abstract: A 1.7 kilobase cDNA clone isolated from a human liver cDNA library contained 822 nucleotides encoding the carboxyl-terminal 274 amino acid sequence of alpha 2-plasmin inhibitor, a stop codon and a 3' noncoding region of 0.9 kilobases. The amino acid sequence deduced from the cDNA shows 29-31% homology with those of other plasma protease inhibitors. The inhibitor's putative reactive-site peptide bond was Met-Ser, and the Met residue was located at the 91st position from the carboxyl-terminal end. The plasminogen binding site was located in the carboxyl-terminal region.
