Release of N-terminal peptides from Glu-plasminogen by plasmin in the presence of fibrin.
The rate of plasmin-catalyzed Glu-plasminogen to Lys-plasminogen conversion was faster in the presence of fibrin than in its absence when assayed by SDS-polyacrylamide gel electrophoresis followed by quantification of stained bands by densitometer. Experiments with the isozymes Glu-plasminogen I and Glu-plasminogen II showed that plasmin-catalyzed formation of Lys-plasminogen II was especially facilitated in the presence of fibrin.
