A novel acetylpolyamine amidohydrolase is described. The enzyme specifically hydrolyzes the amino bond in acetylputrescine, acetylcadaverine, acetylspermidine and acetylspermine with strong substrate affinity. The enzyme is preferably produced by culturing a microorganism belonging to the genus Mycoplana, and is used in the quantitative determination of polyamine contained in a living body sample, which is useful for cancer diagnosis.
本研究描述了一种新型乙酰多胺酰胺水解酶。该酶能特异性地水解乙酰泼尼松碱、乙酰金刚烷胺、乙酰精胺和乙酰精胺中的氨基键,具有很强的底物亲和力。该酶最好是通过培养属于霉浆菌属的微生物产生的,可用于定量测定活体样本中含有的多胺,这对癌症诊断非常有用。
