Each aminoacyl-tRNA synthetase must functionally distinguish its cognate tRNAs from all others. We have determined the minimum number of changes required to transform a leucine amber suppressor tRNA to serine identity. Eight changes are required. These are located in the acceptor stem and in the D stem.
每个氨酰-tRNA合成酶必须在功能上把它对应的tRNA与所有其他tRNA区分开来。我们已经确定了将亮氨酸琥珀抑制tRNA转变为丝氨酸识别特性所需的最少变化数量。需要八个变化。这些变化位于受体茎和D茎中。
