A 576 base-pair DNA encoding human c-Ha-ras protein (p21) with a valine codon at position 12 has been synthesized by ligation of chemically synthesized oligodeoxyribonucleotides. The duplex was inserted into a plasmid with the E. coli tryptophan promoter and was expressed in E. coli efficiently.
一段编码人c-Ha-ras蛋白(p21)的576个碱基对的DNA,其第12位密码子为缬氨酸,已通过化学合成的寡脱氧核糖核苷酸连接而成。该双链体被插入到带有大肠杆菌色氨酸启动子的质粒中,并在大肠杆菌中高效表达。
