Reaction rates of several reference aminoglycoside-modifying enzymes were studied at various substrate concentrations. The resulting concentration-response curves showed wide variation in threshold concentration, in curve slope, in enzyme saturation, and in substrate inhibition. Together, the curves of a defined aminoglycoside panel yielded more specific information for each individual aminoglycoside-modifying enzyme tested than did conventional substrate profiles obtained at a single substrate concentration.
在不同底物浓度下研究了几种参考氨基糖苷修饰酶的反应速率。所得的浓度-反应曲线在阈值浓度、曲线斜率、酶饱和度和底物抑制方面表现出广泛差异。总体而言,对于每种测试的氨基糖苷修饰酶,一组特定氨基糖苷的曲线比在单一底物浓度下获得的传统底物谱提供了更具体的信息。
