Screening of mushrooms having fibrinolytic activity = 혈전용해능을 갖는 버섯류의 탐색

Abstract

Five fungi (mushrooms), Daedaleopsis styracina, Trichaptum abietium, Coriolus versicolor, Pisolithus tinctorius and Tricholomopsis decora, were screened and examined the fibrinolytic activity and specificity. The extracts of mushrooms showed a level of fibrinolytic activity that was about 3-4 times higher than that of plasmin 1.0 unit. In particular, Pisolithus tinctorius of them showed the greatest enzyme activity (4.71 plasmin unit/mL) by fibrin plate assay, and the highest specificity (1.32 plasmin unit/mL) using chromogenic substrate (N-p-Tosyl-Gly-Pro-Lys p-nitroanilide) by Tricholomopsis decora. And the same molecular mass 54 and 61kDa showing the fibrinolytic activity obtained from all fruiting bodies were confirmed, and it was found that Trichaptum abietium and Tricholomopsis decora have a strong fibrinolytic enzyme with an apparent size of 100 kDa and 84 kDa, respectively on SDS-fibrin zymography activity assay.
