Pleurotus and Agrocybe hemolysins, new proteins hypothetically involved in fungal fruiting.
Novel hemolytic proteins, ostreolysin and aegerolysin, were purified from the fruiting bodies of the edible mushrooms Pleurotus ostreatus and Agrocybe aegerita. Both ostreolysin and aegerolysin have a molecular weight of about 16 kDa, have low isoelectric points of 5.0 and 4.85, are thermolabile, and hemolytic to bovine erythrocytes at nanomolar concentrations. Their activity is impaired by mic...
متن کاملHemolysins of Vegetable Origin
1. The sap of Cotyledon scheideckeri possesses hemolysins for the red corpuscles of different animals. 2. The hemolysins of vegetable sap can be bound by erythrocytes and cannot be separated. 3. A definite quantity of erythrocytes is able to extract from the sap only a part of the hemolysins it contains. 4. The quantity of hemolysins in the sap of different plants is subjected to the same fluct...

متن کاملQuantitative Chemical Studies on Hemolysins
1. Total antibody in hemolysins may be estimated from the nitrogen added to sheep stromata suspensions. 2. The method is applied to a number of hemolysins and a correlation, valid to within 20 per cent, established between hemolytic titer and total antibody. 3. When stromata combine with antibody in the presence of guinea pig complement they may take up at least 80 per cent of their weight of c...
متن کاملTissue Hemolysins as Lysin-inhibitor Complexes
1. Lytic substances are enzymatically produced at 37 degrees C. from tissue slices or homogenates (mouse liver, kidney, etc.) and appear in the medium in which the tissue fragments are suspended. Their concentration increases with the time during which the tissue is kept at 37 degrees C. (preincubation), and is accompanied by pH changes, so that the lytic activity as finally measured is a funct...
