| Abstract: | Persson, Y., and Friman, E. 1993. Intracellular proteolytic activity in mycelia of Arthrobotrys oligospora bearing mycoparasitic or nematode trapping structures. Experimental Mycology 17, 182-190. The fungus Arthrobotrys oligospora parasitizes other fungi with the aid of coils and captures and digests nematodes by means of adhesive traps. We have compared proteolytic activities of mycelial extracts from coils and traps with those of vegetative hyphae. A. oligospora produced a number of proteases active at both alkaline and acidic pH. Coil extract had significantly higher proteolytic activity than extracts of vegetative hyphae. Several coil culture-specific bands were found after substrate gel electrophoresis. Pepstatin-sensitive proteolytic activity at acidic pH was higher in coil extract than in normal mycelial extracts, although the total proteolytic activity was the same. No proteolytic activity was connected solely to mycelial extracts with traps and no enhancement of proteolytic activity was observed during infection of nematodes. |
