At least three receptors for chemotaxis toward L-amino acids in Bacillus subtilis could be found with the aid of taxis competition experiments. They are called the asparagine receptor, which detects asparagine and glutamine, the isoleucine receptor, which detects isoleucine, leucine, valine, phenylalanine, serine, threonine, cysteine, and methionine, and the alanine receptor, which detects alanine and proline. Histidine and glycine could not be assigned to one of these receptors. Cysteine and methionine were found to be general inhibitors of chemotaxis and serine was found to be a general stimulator of chemotaxis. Some structural analogues of amino acids were tested for chemotactic activity. The chemotactic activity of B. subtilis is compared with that of Escherichia coli.
借助趋化性竞争实验，在枯草芽孢杆菌中至少可发现三种对L-氨基酸产生趋化作用的受体。它们分别被称为天冬酰胺受体，可检测天冬酰胺和谷氨酰胺；异亮氨酸受体，可检测异亮氨酸、亮氨酸、缬氨酸、苯丙氨酸、丝氨酸、苏氨酸、半胱氨酸和甲硫氨酸；以及丙氨酸受体，可检测丙氨酸和脯氨酸。组氨酸和甘氨酸不能归为这些受体中的任何一种。发现半胱氨酸和甲硫氨酸是趋化作用的通用抑制剂，而丝氨酸是趋化作用的通用刺激剂。测试了一些氨基酸的结构类似物的趋化活性。将枯草芽孢杆菌的趋化活性与大肠杆菌的趋化活性进行了比较。
