Three plasmids named pBSGt pBSGd and pBSGk were constructed respectively with two plasmids named pEGH and pBS305. The plasmid pEGH contained gfp gene and pBS305 is an E. coli -Rhodococcus shuttle vector. These constructed plasmids can be used to detect the efficiency of promoter.

以带有报告基因gfp的质粒pEGH和大肠杆菌-红球菌穿梭载体pBS305为出发质粒，构建了三个带有不同启动子的表达质粒pBSGt、pBSGd和pBSGk，电击转化红平红球菌LY822。

Consequently,in this study we introduced genes that encode the xylose isomerase and xylulokinase precisely under the control of a strong,constitutive glyceraldehydes-3-phosphate promoter by PCR-mediated overlap extension,which is in charge of xylose assimilation;and also we introduced genes that encode the transaldolase and transketolase precisely under the control of enolase promoter,which is in charge of xylose utilization,then transformed plasmid with the two operons into Z.

因此，本文通过代谢工程手段，将负责木糖代谢转化的木糖异构酶基因和木酮糖激酶基因置于强组成型启动子3-P-甘油醛下；同时将负责木糖转化利用的转醛醇酶和转酮醇酶基因置于强组成型启动子烯醇酶下，通过电转的方式将上述四个基因转入到Zymomonasmobilis CP4中，从而在运动发酵单胞菌中构建起一套完整的木糖代谢途径。
