title: Chitinase in female Onchocerca gibsoni and its inhibition by allosamidin.
abstract: Chitinase activity has been detected in female worms of Onchocerca gibsoni. With 3,4-dinitrophenyl-tetra-N-acetylchitotetraoside as substrate 50% of maximum activity was achieved at about 25 microM substrate, with inhibition above 50 microM substrate. The antibiotic allosamidin very strongly inhibited the chitinase activity, 50% inhibition being achieved by 200 pM allosamidin in the presence of 45 microM substrate.
