In Escherichia coli , the key enzyme for biosynthesis of aromatic amino acids, 3 deoxy D arabino heptulosonate 7 phosphate (DAHP) synthase are encoded by three genes, aro G, aro H and aro F. This study showed the expression of E.

• 为了对大肠杆菌中由aroG基因编码的 3 脱氧 D 阿拉伯庚酮糖酸 7 磷酸合成酶 (DAHP合成酶 )进行结构与功能的深入研究 ；尝试了aroG基因在枯草杆菌中的表达 .
