We have constructed a promoter-probe vector utilizing the expression of a promoter-less tyrosinase derived from Streptomyces plasmid pIJ702. The vector, pMX100, has single sites for EcoRI, KpnI, BamHI, XbaI, SalI, and SphI for cloning promoter sequences. When the tac promoter was inserted into pMX100, E. coli harboring the chimeric plasmid produced the melanin pigment.
我们利用源自链霉菌质粒pIJ702的无启动子酪氨酸酶的表达构建了一个启动子探针载体。该载体pMX100具有EcoRI、KpnI、BamHI、XbaI、SalI和SphI的单一位点,用于克隆启动子序列。当将tac启动子插入pMX100时,携带嵌合质粒的大肠杆菌产生了黑色素。
