- 論文の詳細を見る
Two chitinases were purified from the culture filtrate of Streptomyces sp. AJ 9463, which is a producer of a chitinase inhibitor, allosamidin. They had similar molecular masses (44.5kDa and 43.7kDa, estimated by SDS-PAGE) and both of them had slightly acidic optimum pH ranges, but showed quite different sensitivities to allosamidin. One chitinase, termed chitinase S, was strongly inhibited by allosamidin with the IC_<50> value of 0.5μg/ml. The other one, termed chitinase IS, was not inhibited by the drug even at the concentration of 2mg/ml.
