None of the heterologous deoxyribonucleic acid from various bacilli was capable of transforming lysyl- and tryptophanyl-transfer ribonucleic acid (tRNA) synthetase mutants of Bacillus subtilis to wild type. It was concluded that there is little conservation of the aminoacyl-tRNA synthetases even though the tRNA cistrons are conserved genetic functions.
来自各种芽孢杆菌的异源脱氧核糖核酸均无法将枯草芽孢杆菌的赖氨酰和色氨酰转移核糖核酸(tRNA)合成酶突变体转化为野生型。得出的结论是,即使tRNA顺反子是保守的遗传功能,但氨酰-tRNA合成酶的保守性很低。
