Abstract
Aggregative amoebae of Dictyostelium minutum are not attracted by cyclic AMP; they are sensitive to various attracting sources from which yeast extract was chosen to purify the chemoattractant. A small acrasin-like species-specific molecule which contains glycine and C5H5N5 has been purified 30,000-fold. Several characteristics of this chemotactic molecule, which is inactivated by an enzyme that is not species specific, are described.
摘要
微小盘基网柄菌的聚集性变形虫不受环磷酸腺苷的吸引；它们对多种吸引源敏感，从中选择酵母提取物来纯化趋化剂。一种含有甘氨酸和C5H5N5的类似聚集素的小种特异性分子已被纯化了30000倍。描述了这种趋化分子的几个特征，它可被一种非物种特异性的酶灭活。
